Until recently, we talked about replaceable amino acids... Today I turn to the more important group of amino acids - essential.

Essential amino acids are not produced in the body. They come exclusively from food. That is why it is important to monitor the presence of a full-fledged source squirrel in the diet. The absence of any essential amino acid may be a limiting factor, i. E. hinder the assimilation of other amino acids.

Essential amino acids. Valine.

That is why I am opposed to mono diets, raw food diets, and vegetarianism that exclude animal products. Next, we will focus on a group of essential amino acids that have an important effect on the functions of the brain and nervous system. These include valine, isoleucine, leucine, lysine, methionine, threonine, tryptophan, and phenylalanine. Arginine and histidine are also indispensable for children. Let's take a closer look at what we need them for and where to get them.

Valine.

The essential amino acid is named after the famous valerian plant. It is the main substance for the synthesis of vitamin B5 and penicillin. Valine in combination with leucine and isoleucine makes up about a third of the total muscle mass squirrel... Valine is a source of energy for muscles. This keeps the remaining amino acids from being broken down. Valine increases muscle coordination and lowers the body's threshold of sensitivity to such adverse factors as pain, heat, cold. Thus, valine can be considered an important amino acid for the creation and maintenance of a beautiful figure.

Valine is used to treat bad habits and painful addictions: alcoholism, smoking, drug addiction, as well as depression and multiple sclerosis.

The daily requirement for valine is 4 grams. Below is a table with data on the content of valine in products. nutrition.

Valine belongs to one of the few amino acids that our body does not reproduce. This substance should enter the body only from the outside, along with food. This substance will be discussed in the article.

Its scientific name is 2-amino-3-methylbutanoic acid, or aliphatic α-amino acid, one of the 20 proteinogenic amino acids, is part of almost all known.

Chemical formula: C5H11NO2

Did you know? The human body contains 5 million proteins: all of them are formed by only 22 types of amino acids.

It is one of the essential amino acids. It promotes the absorption and assimilation of other amino acids, participates in the synthesis of proteins, in particular, determines their structure. It is also the basis for the synthesis.

But still, its main role is to support the health and tone of the muscles of a person, his immune system. The liver, if necessary, converts this amino acid into glucose, and sends it to the muscles.

It is also important for human mental health and liver health, it takes part in the removal of toxic substances from their body.
As a prophylaxis, it is used against brain damage and for the treatment of liver diseases (hepatitis, cirrhosis).

Main functions and benefits

Valine is really an essential amino acid: without it, the human body has a very hard time.

In the first years of life, the child becomes vulnerable to disease, especially when the mother's antibodies cease to protect him. And this is where the correct intake of valine becomes extremely important. After all, it is he who forms and supports the baby's immune system.

A growing body also requires this amino acid to build and strengthen muscles.

Its role also increases during active mental stress, which children have during their studies. Also used to support mental health.

For adults

But valine is not just for the development of children. Adults should also monitor their intake of this substance. After all, it has the following properties:

• increasing endurance and resistance to extreme situations;
• helps with the growth and development of muscles;
• does not allow the level of serotonin (the hormone of joy) to decrease;
• removes excess nitrogen from the body;
• helps with liver and kidney diseases. Used in the treatment of addictions (alcohol, drugs);
• increases the feeling of fullness and is used in diets and in the treatment of obesity.
• strengthens the immune system.

We can only get it with food. Therefore, it is important to determine where it is contained in sufficient quantities.

Dairy products are literally saturated with this amino acid, cheeses. Even a small amount of these foods can provide you with your daily valine requirement.
There is a lot of it in eggs, meat, fish. Especially it is worth paying attention to quail eggs - the digestibility of this substance in them is very high.

From plant products, they are rich in legumes (beans, peas), seeds and sunflowers, pine nuts and hazelnuts.

Daily requirement and rate

A healthy person needs 2-4 grams of this amino acid per day. But this is a general average. More precisely, your rate can be calculated based on the indicator of 10 mg of valine per 1 kg of human weight.

Important! In case of disorders of the liver and kidneys, only a doctor selects the rate of valine consumption. It is extremely dangerous to independently engage in such an appointment.

About excess and lack

As you can see, this substance is useful and necessary. Its disadvantage is quite dangerous. But it is also undesirable to allow excess.

Excess

In case of an overdose, problems with the nervous system begin, chills, numbness and tingling in the extremities, hallucinations appear. There are disorders in the digestive system, blood flow becomes more complicated, liver and kidney dysfunctions appear.

With a deficiency, degenerative changes in the body begin:

• immunity is weakened;
• memory deteriorates, sleep is disturbed;
• the level of serotonin decreases, as a result, mental disorders, depression appear;
• dermatitis and other skin rashes.

Decreased valine content makes it harder for other amino acids to be absorbed.

Did you know? The name of the amino acid "valine" comes from the valerian plant.

Most often, a deficiency occurs with diets, especially protein. In this case, you should carefully select the composition of foods for the diet.

Interaction with other substances

This amino acid actively reacts to proteins, polyunsaturated fatty acids, interacts well with "long" carbohydrates (cereals, vegetables, wholemeal bread, bread, muesli). And it also goes well with its "colleagues" - the amino acids of the protein group.

One of its functions is to help muscle growth and strength and to reduce cortisol levels.
Therefore, it is included in the diet of bodybuilders and other athletes in protein shakes.

So, valine is an important component of our body. It helps in strengthening muscles, relieves stress, and is beneficial for athletes and workaholics. It is found in many foods, and getting the amount you need is not difficult.

General characteristics of valine

Valine belongs to the group of proteinogenic amino acids, which includes 20 acids. This aliphatic α-aminoisovaleric acid has the chemical formula: C 5 H 11 NO 2.

It acts as one of the starting substances in the synthesis of pantothenic acid (vitamin B3) and penicillin. Interferes with the decrease in the level of serotonin in the body. It is found in large quantities in animal products, rice and nuts.

Daily Valine Requirement

For an ordinary person, the daily norm of valine is, on average, 3-4 grams per day. Regular chicken eggs are in the lead in terms of the content of this substance, followed by cow's milk and meat. For vegetarians, nuts, beans, rice, pumpkin seeds, and seaweed are good choices.

The need for valine increases:

• in the treatment of painful addictions and addictions;
• with depression;
• in the presence of multiple sclerosis;
• when restoring damaged tissues;
• with a deficiency of amino acids resulting from the intake of certain medications;
• if you suffer from insomnia, irritability and nervousness;
• with increased sensitivity to temperature changes.

The need for valine decreases:

• with paresthesias (sensations of goose bumps on the skin);
• with sickle cell anemia;
• with violations of the gastrointestinal tract.

Valine digestibility

Since valine is an essential acid, its assimilation occurs through general interaction with the amino acids L-leucine and L-isoleucine. In addition, valine is very well absorbed from walnuts and quail eggs.

Useful properties of valine and its effect on the body

• valine prevents a decrease in the level of serotonin - the hormone of joy and good mood;
• regulates protein metabolism;
• is a complete source of energy for muscle cells;
• thanks to valine, vitamin B3 is synthesized;
• valine is responsible for the assimilation of other acids of the proteinogen group;
• increases muscle coordination and reduces the body's sensitivity to cold, heat and pain;
• Valine is essential for maintaining normal nitrogen levels in the body.

Interaction of Valine with Essential Elements

Valine is able to interact well with proteins, polyunsaturated fatty acids, as well as slowly digestible carbohydrates (cereals, vegetables, wholemeal bread, bread, muesli). In addition, valine is combined with all amino acids of the protein group.

Factors affecting the body's valine content

Adequate nutrition and overall physical health affect the body's valine content. Problems in the functioning of the gastrointestinal tract lead to a decrease in the absorption of this amino acid by the cells of the body. Lack of enzymes, diabetes mellitus, liver disease lead to a decrease in the positive effect of amino acids on the body as a whole.

Valine for beauty and health

Valine is used in bodybuilding as a dietary supplement in combination with essential amino acids such as isoleucine and leucine. Such complexes of sports nutrition tone muscle tissue and strengthen the muscles. Used to build muscle mass.

Since valine is responsible for providing our body with serotonin, a sufficient amount of it in the body leads to vigor, good mood and bright eyes. In sports nutrition, valine is also used as a means to improve protein metabolism.

Based on this, we can conclude that in order to feel good and look beautiful, you should consume products containing valine. Naturally, within normal limits.
