Proteins are one of the most important components of food. It is the amino acid composition that determines its value. Proteins are essential for building cells, tissues of the human body and maintaining many vital functions.

Amino acids in food

The content of essential amino acids in foods determines their biological value for the body. The biological value of protein is also determined by the degree of assimilation by the body after digestion. The degree of digestion, in turn, depends on several factors. What state is the body in, the activity of its enzymes and the depth of hydrolysis in the intestine. Also, the degree of digestion largely depends on pre-treatment protein in cooking. Rubbing, grinding, boiling and heat treatment facilitate and accelerate the processes of digestion and assimilation of protein, especially plant origin.

Foods rich in amino acids

Consider which products contain. Food is the main source of essential amino acids. Animal and vegetable proteins in without fail must be present in daily diet person. The amino acid saturation of vegetable and animal protein is different, so it is necessary to monitor their correct combination. It is best to eat meat and fish with flour products, milk with cereals, eggs with potatoes.

Products with high content Amino acids are necessary for a person in the same way as air, so you should pay enough attention to protein foods when compiling a diet.

Amino acids in products table

Essential amino acids in foods

Most often in the diet there is a lack of three amino acids, which is why it is customary to evaluate products containing protein by the amount of their content.

So, consider which foods contain the amino acids methionine, tryptophan and lysine.

Methionine it is mostly found in dairy products, but it is also found in acceptable amounts in fish, meat and eggs. Among the representatives of vegetable protein, legumes and buckwheat can boast the presence of methionine.

tryptophan found in eggs, cheese, fish, cottage cheese and meat. However, in meat, the percentage of its content is different, depending on the part of the carcass. IN connective tissues(neck, shank) it is very small, but in the pulp and tenderloin it is more than enough. Among plant foods, beans, peas and soybeans are rich in tryptophan.

Lysine contain all dairy products, as well as cheese, egg yolk, cottage cheese, fish, meat and plants of the legume family.

Free amino acids in foods

Free amino acids in foods are found in scanty amounts. Most of them are part of those proteins that are hydrolyzed under the influence of protease enzymes in the gastrointestinal tract. An amino acid molecule that is not associated with other molecules is very quickly absorbed into the bloodstream directly from the intestines and prevents muscle breakdown. That's why free amino acids are very popular, despite their high cost. Digestion is a rather energy-intensive and lengthy process, and free amino acids are the best way to quickly supply an athlete's body with protein.

Sulfur-containing amino acids include taurine. In the body, it is present in the central nervous system and, in particular, in the brain. On average, the content of taurine is 1 g per kilogram of body weight. The main sources of this amino acid are any fish and seafood (eg, crabs). IN in kind he meets in mother's milk and some types of meat.

With a low level of taurine in the body, heart muscle diseases can develop, retinal development disorders appear, and skeletal growth can slow down.

Taurine is involved in energy processes, promotes the removal of toxins from the body. It regulates the concentration of calcium and cell membrane. Taurine takes part in the process of formation and maintenance good health, for example, plays a role in fluid normalization in muscle cells, has an effect on insulin, on the digestion of fatty foods, on metabolism, on cholesterol levels, on the immune system, on the production of bile, sperm. Taurine is essential for optimal development and functioning of the central nervous system, it renders useful action , mental activity, when generating extreme energy.

What foods contain cystine and methionine

Cystine is a non-essential sulfur-containing amino acid. It aids in the digestion process, can neutralize some toxic substances, and protects the body from radiation. Cystine is one of the most powerful antioxidants, its action is enhanced by the simultaneous intake of selenium and vitamin C. This amino acid contains food with high level protein: meat, chicken, fish, dairy products, seeds, nuts, legumes, oats. Some amount of cystine is present in broccoli, Brussels sprouts, onions, garlic, red peppers.

A lack of methionine can lead to atherosclerosis.

Methionine is one of the essential sulfur-containing amino acids. It is required for the biosynthesis of biologically important compounds in the body. This substance contributes to the normalization fat metabolism, has a moderate antidepressant effect, participates in the development immune cells, plays important role for the normal functioning of the nervous system. Methionine has a stimulating effect on cholesterol metabolism, restores cells and liver, helps to remove toxins from the body, improves overall tone, and prevents excessive fat deposition.

Methionine is found in following products food: meat, eggs, fish, sesame seeds, cereals (oats, wheat), almonds, corn, beans, peanuts, lentils, brown rice, buckwheat, barley, semolina, millet groats. The largest number of this amino acid is found in chicken and beef meat, beef liver, eggs, cod.

It is known that for a full-fledged existence, a person needs not only fats, proteins, carbohydrates and vitamins, but also microelements, one of which is selenium. Its importance cannot be overestimated, but, unfortunately, more and more doctors are diagnosing selenium deficiency, which is the cause of many functional disorders. You can make up for this deficiency with proper nutrition.

Why does the body need selenium?

The main property of selenium, the most important organism, is its antitumor activity. It activates the p53 gene, important element endocrine system, which is responsible for redox reactions and is part of cell detoxifying enzymes that neutralize free radicals. In the event that a person has reduced production of this gene in the body, selenium is vital for the prevention oncological diseases.

It is also an indispensable participant in the metabolism of proteins and nucleic acids, participates in anti-inflammatory and regenerative processes, supports and strengthens the immune system, helping it fight diseases such as viral hepatitis, herpes, Ebola. Thanks to selenium, the immune system can keep the HIV virus in a latent state, preventing its development and transition to the full picture of AIDS.

Selenium is essential for the treatment of hyperplasia thyroid gland, together with iodine preparations, it is also used for the prevention of thyroid diseases.

Selenium is essential for normal operation cardiovascular system, removing salt from the body heavy metals: lead, cadmium, mercury, manganese. It is also found in the enzyme glutathione peroxidase, which is part of the body's global antioxidant system, protecting against the effects of free radicals. Selenium helps the body cope with arrhythmia, reduces the risk of fibrillation and toxic substances.

What foods are rich in selenium

The most selenium-rich vegetables and cereals grown on soils, in which there is a sufficient amount of this microelement. Selenium in large quantities found in garlic and onions brazil nuts and mushrooms, they are rich in wheat, seeds. From animal food The main sources of selenium include all seafood, including fish, mussels and other shellfish, shrimp and squid. There are a lot of it in and and kidneys, meat,.

Selenium is found in some medicinal plants: spirulina algae, silver birch, eucalyptus, Ural licorice, sweet clover, field ephedra and horsetail.

Enough bad cholesterol found in fatty dairy products: whole, butter, cheese, and . It is also present in margarine. A lot of cholesterol in dishes such as potatoes and pies, meatballs, Fried fish and steaks.

How to lower the amount of cholesterol in the blood

First of all, it is necessary to review the diet, excluding the above products from it, or at least significantly reducing their consumption. From fried foods should be abandoned altogether, and fatty meat should be replaced with nutritious and healthy marine fish. The latter product, by the way, contains protein, which is absorbed by the body much better than meat.

It is also useful to eat foods that lower blood cholesterol levels more often. These include: oatmeal and buckwheat, various nuts, prunes, legumes, peppers, vinegar and mustard. As well as some types of fish, such as tuna, salmon, halibut and sardines. It is also important to eat more fresh vegetables and fruits. Only they should be filled not with sour cream and mayonnaise, but with unrefined vegetable oil cold pressed.

As for drinks, it is better to exclude any coffee from the diet, and replace black tea completely or at least partially with green and herbal tea. It is also useful to drink more freshly squeezed juices and mineral water.

And, of course, sports or even ordinary long walks at any time of the day, as well as the rejection of bad habits in the form of alcohol and tobacco.

Tip 7: What foods are good for mental activity

Scientists have long conducted experiments to identify foods that contribute to the development of the level of intelligence, improve memory and attentiveness. After various studies doctors have come to the conclusion that many foods that are good for the heart have a beneficial effect on the development of a person’s mental abilities.

Among the foods that are good for the human mind, scientists highlight cranberries. This product, according to scientists, improves memory. Cranberries contain a lot of antioxidants that bind with oxygen radicals, which has a beneficial effect on improving memory.

Blueberries have similar qualities. These berries contain the same antioxidants, but in a slightly smaller amount. Blueberries are also believed to help improve eyesight.

Among the foods that have a beneficial effect on mental activity, scientists distinguish ordinary large-leaved beets and cabbage. These vegetables contain substances that destroy enzymes that contribute to the development of cognitive decline diseases.

A special place in food products that have a beneficial effect on mental capacity man is occupied by a fish. In particular, salmon and Atlantic herring contain substances that have a beneficial effect on brain activity and greatly reduce the likelihood of Alzheimer's disease.

In addition, you can select other products that affect the beneficial activity of the brain. For example, oranges, avocados, walnuts, olive oil.

What is sulfur for?

Many life-support processes depend on the balance of sulfur in the body. This is one of the five most important bioelements on planet Earth. Sulfur is part of all proteins, without exception. Thanks to this macronutrient, skin, hair and nails retain good appearance. Sulfur is involved in the metabolic process, has an anti-allergic effect, improves the functioning of the nervous system, increases human immunity, controls the processes of blood clotting, as well as the absorption and synthesis of B vitamins, extinguishes foci of inflammation, reduces joint and muscle pain and cramps, neutralizes toxins. With its participation, the synthesis of important amino acids is produced and insulin is produced.

An adult needs to consume at least 500-1200 mg of sulfur daily. Daily rate for children is 30-40% less. Athletes and people who need to increase body weight require up to 3000 mg of sulfur. Sulfur deficiency in the body is extremely rare. It usually manifests itself in the form of a deterioration in the condition of the hair and nails. The skin becomes dull and gray, blood sugar, cholesterol and triglycerides rise. There is tachycardia and hypertension, the person suffers from pain in the joints. In the most severe cases of serodeficiency, there are fatty degeneration liver, hemorrhages in the kidneys, severe violations work of the nervous system and protein metabolism.

As a rule, sulfur deficiency can be compensated with balanced nutrition, it does not require the use of special medicines.

Products containing sulfur

Sulfur predominates in protein products, i.e. in products of animal origin. Therefore, sulfur deficiency most often occurs in vegetarians who eat only plant products. The leader in sulfur content is beef (230 mg/100 g). More than 200 mg per 100 g of product is found in sea ​​fish: chum salmon, horse mackerel, sea, cod. From chicken meat, you can get 180-184 mg of sulfur per 100 g of product. Sulfur-rich and chicken eggs - 177 mg / 100 g. Dairy products with a high sulfur content include ice cream (37 mg / 100 g), milk (28 mg / 100 g) and hard cheeses, such as Dutch (25 mg / 100 g).

Sulfur sources are also plant products. With a sulfur deficiency, it is worth diversifying the diet with oatmeal and buckwheat, legumes, onions and garlic, gooseberries, grapes, all types of cabbage, juice, apricots, peaches, pumpkins, melons. In order to stimulate the formation of melanin, you can use legumes, such as soy. Melanin is most actively produced under the influence of sun rays, so you should walk more often at those moments when the sun is shining in the sky.

However, there are products that contain substances that hinder the production of melanin. These include: smoked foods, pickles and marinades, alcohol, coffee, chocolate, vitamin C.

rebuilding on healthy lifestyle life, it is necessary to establish the supply of a complete set of useful elements. You should strive to eat food filled with natural vitamins (take them if they are deficient), useful minerals and antioxidants. There is another block of substances that affect the state of health and appearance. These are amino acids.

They are a component of proteins. Hence, their importance in the human body is fundamentally important. And, therefore, everyone who monitors their health should study in which products these vital elements can be found.

General characteristics: the role of amino acids in the body

The fundamental role of amino acids is in the formation of the body. Of particular importance is the growth process in childhood. Amino acids are primarily protein building material representing a large proportion of the cell.

They are proteins - multi-component organic substances, the composition of which is saturated with the structural components of amino acids. This, in turn, means that amino acids directly affect the structure of tissues and internal organs person. In addition, they are actively involved in the work of the immune, hormonal and other vital systems.

Amino acids are divided into 2 groups: interchangeable, which the body synthesizes itself, and irreplaceable , the intake of which should be provided with food. With a lack of the latter, the body consumes the substances accumulated in the muscles.

It is necessary to take into account the composition of which products contain amino acids in order to correctly combine them.

When compiling a list of products saturated with amino acids, you need to remember the gradation of proteins into variants of plant and animal origin. The latter are easier to perceive by the human body.

Of the foods rich in vegetable protein, the most popular are legumes and cereals. But vegetable protein sources may not have the required amino acids. When alternating and combining products of both types of origin increases nutritional value protein.

The dose of amino acids necessary for a person

Daily dose of amino acids, necessary for the body, — 1-2 grams per day . But there are circumstances that require a significant increase in the intake of amino acids:

• body growth,
• exclusion from the use of food of animal origin,
• periods of illness and rehabilitation,
• stress and wrong way of life,
• some chronic diseases
• intense physical and mental stress.

Lack of amino acids leads to ailments and pain in the muscles chronic fatigue, lowering the quality of mental activity, difficulties with gastrointestinal tract and immunity. Obvious manifestations of amino acid deficiency are hair loss, drowsiness and weakness, loss of appetite. Skin deterioration, developmental delay, low resistance are also likely infectious diseases, early gray hair.

List of amino acids and foods that contain them

1. Valine necessary for the activation of mental activity. It is found in food as a vegetable ( cereals, beans ), and animal origin ( milk and meat products );
2. Isoleucine helps to bear heavy physical exercise. Is in chicken eggs, poultry, liver, beans, cashews and almonds ;
3. Leucine promotes the regeneration of skin, muscles, bone tissue. His body can get from nuts, rice (brown variety), plus fish or meat ;
4. Sources of Threonine – milk and eggs . He is responsible for efficient work cardiovascular system and the formation of tooth enamel;
5. Methionine affects the activity of the kidneys and liver, accelerates the detoxification of the body. I'm rich milk, fish, meat ;
6. tryptophan responsible for good mood, acquired from bananas, sesame, dates ;
7. Lysine, famous for its antiviral effect, is part of dairy products and cereals . It also improves the functionality hormonal system and collagen synthesis;
8. Phenylalanine participates in ensuring the output of metabolic results, stabilizes the functioning of the nervous system, improves memory. He is in fish dishes, chicken and dairy products .

Amino acids for beauty

In addition to the listed amino acids, it is worth noting some, the saturation of which affects the appearance and youth of the fair sex. They provide the production of elastin, which tightens the skin, and makes hair and nails strong and healthy.

These include: cysteine ​​(rich in chicken eggs, sesame, corn, rice ) And linoleic acid(searched for in oils from wheat germ or rice, soy or grape seed ).

Free amino acids

Free amino acids are present in food in a minimal dose. The main part of them is included in the components of proteins digested in the gastrointestinal tract. Each amino acid molecule that is not connected to other molecules, for a short time enters the bloodstream directly from the intestines, which prevents muscle breakdown. That's why such amino acids are incredibly in demand in sports nutrition, despite high cost . Digestion is a long-term and energy-consuming procedure, and free amino acids are preferable to others for the immediate provision of protein to the exercising.

A well-designed diet should include a balanced amount of essential amino acids. Knowing where to look for them, everyone will be able to correctly form a daily menu.

Sometimes amino acids are taken in the form biological additives. Among adherents of active training, a special sports nutrition containing amino acids. But this is allowed only for those who have been prescribed dietary supplements by a doctor or an experienced fitness trainer. It is much safer to get amino acids from natural products.

Amino acids, being integral part proteins play an important role in the human body. Therefore, it is necessary to know which foods contain amino acids.

What foods contain amino acids? This question is often asked by parents who want their children to grow up healthy. The role of amino acids is to ensure the growth of the body, which is especially important in childhood. They are the main construction material for proteins that make up most of the dry matter of the cell.

General characteristics of amino acids

Proteins or proteins are complex organic substances consisting of separate structural components of amino acids. All amino acids are divided into two large groups: irreplaceable, which must be supplied with food, and nonessential - the human body is able to synthesize them on its own.

Of the 20 amino acids that make up our body, eight belong to the group of essential ones: valine, methionine, leucine, lysine, isoleucine, threonine, tryptophan, phenylalanine, and for children, arginine and histidine. It is important to know which foods contain amino acids and combine them correctly.

What foods contain amino acids

valine is found in animal products (meat, dairy products) and plant origin (legumes, cereals);
leucine is supplied to the body from brown rice, nuts, as well as fish and meat;
isoleucine can be obtained from chicken eggs and meat, liver, legumes, almonds and cashews;
methionine is found in milk, fish, meat;
the main sources of lysine are dairy products and cereals;
threonine is rich in eggs and dairy products;
tryptophan the body receives from dates, sesame seeds, bananas;
Phenylalanine comes from chicken, fish and dairy products.
Proteins of vegetable and animal origin

When listing which foods contain amino acids, it is necessary to mention the division of proteins into proteins of animal and vegetable origin. The former are better absorbed by the human body. As for foods that contain vegetable protein, the most useful of them are legumes and cereals. However, some plant proteins may lack essential amino acids. The combination of products of plant and animal origin increases biological value squirrel.

Functions of essential amino acids

Apart from common functions characteristic of all amino acids, each of the 8 essential amino acids performs specific functions. Lysine and tryptophan are needed by the body for growth. Phenylalanine is involved in the formation of neurotransmitters and plays an important role in the functioning of the adrenal glands. Isoleucine and leucine are associated with the activity of the thyroid gland. Methionine regulates lipid metabolism.

Each meal should contain the optimal amount of essential amino acids. Knowing which foods contain amino acids, everyone can make the right menu.

Everyone knows from chemistry lessons that amino acids are the “building blocks” for building proteins. There are amino acids that our body is able to synthesize on its own, and there are those that are supplied only from the outside, along with nutrients. Consider amino acids (list), their role in the body, from what products they come to us.

The role of amino acids

Our cells constantly have a need for amino acids. Food proteins are broken down in the intestines into amino acids. After that, amino acids are absorbed into the blood stream, where new proteins are synthesized, depending on genetic program and body requirements. The essential amino acids listed below are obtained from foods. Replaceable organism synthesizes independently. In addition to the fact that amino acids are the structural components of proteins, they also synthesize various substances. The role of amino acids in the body is enormous. Non-proteinogenic and proteinogenic amino acids are precursors of nitrogenous bases, vitamins, hormones, peptides, alkaloids, rometors, and many other significant compounds. For example, vitamin PP is synthesized from tryptophan; hormones norepinephrine, thyroxine, adrenaline - from tyrosine. Pantothenic acid formed from the amino acid valine. Proline is the protector of cells from many stresses, such as oxidative stress.

General characteristics of amino acids

Proteins are nitrogen-containing high-molecular organic compounds that are created from amino acid residues and are connected by peptide bonds. In a different way, these are polymers, in which amino acids act as monomers. The structure of a protein includes hundreds, thousands of amino acid residues connected by peptide bonds. The list of amino acids that are found in nature is quite large, about three hundred of them have been found. According to their ability to enter into the composition of proteins, amino acids are divided into proteinogenic (“giving birth to protein”, from the words “protein” - protein, “genesis” - to give birth) and non-proteinogenic. In a living organism, the number of proteinogenic amino acids is relatively small, there are only twenty of them. In addition to these standard twenty, modified amino acids can be found in proteins, they are derivatives of ordinary amino acids. Non-proteinogenic include those that are not part of the protein. There are α, β and γ. Everything protein amino acids are α-amino acids, they have a characteristic structural feature, which can be observed in the image below: the presence of amine and carboxyl groups, they are connected in the α-position by a carbon atom. In addition, each amino acid has its own radical, which is not the same with all in structure, solubility and electric charge.

Types of amino acids

The list of amino acids is divided into three main types, these include:

. Essential amino acids. It is these amino acids that the body cannot synthesize on its own in sufficient quantities.

. Replaceable amino acids. This type of organism can independently synthesize using other sources.

. Conditionally essential amino acids. The body synthesizes them on its own, but in insufficient quantities for its needs.

Essential amino acids. Content in products

Essential amino acids can be obtained by the body only from food products or supplements. Their functions are simply irreplaceable in the formation of healthy joints, beautiful hair, strong muscles. What foods contain amino acids of this type? The list is below:

Phenylalanine - dairy products, meat, germinated wheat, oats;

Threonine - dairy products, eggs, meat;

Lysine - legumes, fish, poultry, sprouted wheat, dairy products, peanuts;

Valine - cereals, mushrooms, dairy products, meat;

Methionine - peanuts, vegetables, legumes, lean meats, cottage cheese;

Tryptophan - nuts, dairy products, turkey meat, seeds, eggs;

Leucine - dairy products, meat, oats, sprouted wheat;

Isoleucine - poultry meat, cheese, fish, sprouted wheat, seeds, nuts;

Histidine - sprouted wheat, dairy products, meat.

Functions of essential amino acids

All these "bricks" are responsible for the most important functions human body. A person does not think about their number, but with their lack, the work of all systems immediately begins to deteriorate.

Leucine the chemical formula is as follows - HO₂CCH(NH₂)CH₂CH(CH₃)₂. This amino acid is not synthesized in the human body. Included in natural proteins. It is used in the treatment of anemia, liver diseases. Leucine (formula - HO₂CCH(NH₂)CH₂CH(CH₃)₂) for the body per day is required in an amount of 4 to 6 grams. This amino acid is a component of many dietary supplements. How food supplement it is coded as E641 (flavor enhancer). Leucine controls the level of blood glucose and leukocytes, when they increase, it activates the immune system to eliminate inflammation. This amino acid plays an important role in muscle formation, bone fusion, wound healing, and also in metabolism.

Amino acid histidine- an important element in the period of growth, when recovering from injuries and illnesses. Improves the composition of the blood, the work of the joints. Helps absorb copper and zinc. With a lack of histidine, hearing is weakened, muscle tissue becomes inflamed.

Amino acid isoleucine involved in the production of hemoglobin. Increases stamina, energy, controls blood sugar levels. Participates in the formation muscle tissue. Isoleucine reduces the effects of stress factors. With its lack, feelings of anxiety, fear, anxiety arise, fatigue increases.

Amino acid valine- an incomparable source of energy, renews muscles, keeps them in good shape. Valine is important for the repair of liver cells (for example, in hepatitis). With a lack of this amino acid, coordination of movements is disturbed, and skin sensitivity may also increase.

Methionine- an essential amino acid for liver function, digestive system. It contains sulfur, which helps prevent diseases of the nails and skin, helps in hair growth. Methionine fights toxicosis in pregnant women. With its deficiency in the body, hemoglobin decreases, fat accumulates in the liver cells.

Lysine- this amino acid is an assistant in the absorption of calcium, contributes to the formation and strengthening of bones. Improves hair structure, produces collagen. Lysine is an anabolic that allows you to build up muscle mass. Participates in the prevention of viral diseases.

Threonine- improves immunity, improves the functioning of the digestive tract. Participates in the process of creating collagen and elastin. Does not allow fat to be deposited in the liver. Plays a role in the formation of tooth enamel.

tryptophan is the main responsible for our emotions. The well-known happy hormone serotonin is produced by tryptophan. With its norm, the mood rises, sleep normalizes, biorhythms are restored. It has a beneficial effect on the work of the arteries and the heart.

Phenylalanine participates in the production of norepinephrine, which is responsible for the wakefulness of the body, activity and energy. It also affects the level of endorphins - hormones of joy. Phenylalanine deficiency can lead to the development of depression.

Replaceable amino acids. Products

These types of amino acids are produced in the body during metabolism. They are taken from other organic matter. The body can automatically switch to create the necessary amino acid. What foods contain essential amino acids? The list is below:

Arginine - oats, nuts, corn, meat, gelatin, dairy, sesame, chocolate;

Alanine - seafood, egg whites, meat, soy, legumes, nuts, corn, brown rice;

Asparagine - fish, eggs, seafood, meat, asparagus, tomatoes, nuts;

Glycine - liver, beef, gelatin, dairy products, fish, eggs;

Proline - fruit juices, dairy products, wheat, meat, eggs;

Taurine - dairy, produced in the body from vitamin B6;

Glutamine - fish, meat, legumes, dairy products;

Serine - soy, wheat gluten, meat, dairy products, peanuts;

Carnitine - meat and offal, dairy, fish, red meat.

Functions of non-essential amino acids

Glutamic acid , whose chemical formula is C₅H₉N₁O₄, in living organisms is included in the composition of proteins, is found in some low molecular weight substances, as well as in a consolidated form. A large role is intended to participate in nitrogen metabolism. Responsible for brain activity. Glutamic acid (formula C₅H₉N₁O₄) converts to glucose during prolonged exercise and helps produce energy. Glutamine plays a big role in increasing immunity, restores muscles, creates growth hormones, and speeds up metabolic processes.

Alanine - the most important source energy for the nervous system, muscle tissue and brain. By producing antibodies, alanine strengthens the immune system, it also participates in the metabolism of organic acids and sugars, and it turns into glucose in the liver. Thanks to alanine, acid-base balance is maintained.

Asparagine refers to non-essential amino acids, its task is heavy loads reduce the formation of ammonia. Helps resist fatigue, converts carbohydrates into muscle energy. Stimulates the immune system through the production of antibodies and immunoglobulins. Aspartic acid balances the processes taking place in the central nervous system, it prevents excessive inhibition and excessive excitation.

Glycine- an amino acid that provides oxygen to the processes of cell formation. Glycine is needed to normalize blood sugar levels, blood pressure. Participates in the breakdown of fats, in the production of hormones responsible for the immune system.

Carnitine is an important transport agent that moves fatty acids into the mitochondrial matrix. Carnitine is able to increase the effectiveness of antioxidants, oxidizes fats, promotes their removal from the body.

Ornithine is a manufacturer of growth hormones. This amino acid is essential for immune system and liver, participates in the production of insulin, in the breakdown fatty acids, in the processes of urination.

Proline - participates in the production of collagen, which is necessary for connective tissues and bones. Supports and strengthens the heart muscle.

Serene- Producer of cellular energy. Helps store muscle and liver glycogen. Participates in strengthening the immune system, while providing it with antibodies. Stimulates the functions of the nervous system and memory.

Taurine favorably affects cardiovascular system. Lets you control epileptic seizures. It plays an important role in the control of the aging process. Reduces fatigue, frees the body from free radicals, lowers cholesterol and blood pressure.

Conditionally essential amino acids

Cysteine contributes to the elimination of toxic substances, takes part in the creation of muscle tissue and skin. Cysteine ​​is a natural antioxidant that cleanses the body of chemical toxins. Stimulates the work of white blood cells. Found in foods such as meat, fish, oats, wheat, soy.

Amino acid tyrosine helps fight stress and fatigue, reduces anxiety, improves mood and general tone. Tyrosine has an antioxidant effect, which allows you to bind free radicals. Plays an important role in the metabolic process. Contained in meat and dairy products, in fish.

Histidine helps to recover tissues, promotes their growth. Found in hemoglobin. Helps in the treatment of allergies, arthritis, anemia and ulcers. With a deficiency of this amino acid, hearing may be impaired.

Amino acids and protein

All proteins are created by peptide bonds with amino acids. The proteins themselves, or proteins, are macromolecular compounds that contain nitrogen. The very concept of "protein" was first introduced in 1838 by Berzelius. The word comes from the Greek "primary", which means the leading place of proteins in nature. Proteins give life to all life on Earth, from bacteria to the complex human body. In nature, there are many more of them than all other macromolecules. Protein is the foundation of life. Of the body weight, proteins make up 20%, and if we take the dry mass of the cell, then 50%. The presence of a huge number of proteins is due to the existence of various amino acids. They, in turn, interact and create polymer molecules. The most outstanding property of proteins is their ability to create their own spatial structure. IN chemical composition protein constantly contains nitrogen - approximately 16%. The development and growth of the body is completely dependent on the functions of protein amino acids. Proteins cannot be replaced by other elements. Their role in the body is extremely important.

Functions of proteins

The need for the presence of proteins is expressed in the following essential functions these compounds:

Protein plays leading role in development and growth, being a building material for new cells.

Protein controls the processes of metabolism during the release of energy. For example, if the food consisted of carbohydrates, then the metabolic rate increases by 4%, and if from proteins, then by 30%.

Due to their hydrophilicity, proteins regulate the water balance in the body.

They improve the functioning of the immune system through the synthesis of antibodies, and they, in turn, eliminate the threat of disease and infection.

Protein in the body is the most important source of energy and building material. It is very important to follow the menu and consume protein-rich foods daily, they will give the necessary vital energy, strength and protection. All of the above products contain protein in their composition.
