The Usefulness of Amino Acid Usage

If you have not heard, amino acids are the “building blocks” of all proteins. In the body, all proteins and muscle tissue are formed using a unique sequence of 21 different amino acids. Considering the chemical structure, amino acids belong to the amino group with the nitrogen atom, which is the basis of this group.

Amino acids are the only components that can form tissues, organs, muscles, skin and hair. And all thanks to the presence of a nitrogen atom, which distinguishes amino acids from other nutrients in the daily diet, such as carbohydrates.

 Today, when most people think about the required amount of protein, it is automatically associated with work on the muscles and bodybuilding. But, we must remember that amino acids are important components of the diet of absolutely all people, especially those who are engaged in any form of physical activity. These chemical elements, as a rule, can be divided into three categories: essential, semi-replaceable, and replaceable.

Essential Amino Acids

What exactly is meant by the name “essential amino acids”? This means their essential importance for the body. These substances are not produced and not synthesized by the body independently, respectively, we need to eat them with food. There are 9 essential amino acids, including the famous BCAA . BCAAs include leucine, isoleucine, and valine.

Among the 9 essential amino acids, 3 of these are subcategories of branched-chain amino acids. These three amino acids are leucine, isoleucine and valine. BCAAs have a chemically unique structure, unlike other essential amino acids. For this reason, they contribute to the appearance of a number of chemically specific features. Compared with other amino acids, BCAAs are absorbed by the body faster and at a faster rate, with the result that absorption does not occur in the stomach, and directly these amino acids are delivered and absorbed in the muscles that need them.

Other essential amino acids

The remaining essential amino acids are histidine, methionine, phenylalanine, tryptophan, threonine and lysine. All of them perform the most important physiological functions in the body.


Histidine is an aromatic amino acid that has a number of vital tasks in the body. Helps to synthesize hemoglobin, contributes to the functioning of the immune system and tissue repair. Histidine can be called a necessary amino acid for those who recover after an illness and are in an active period of growth.


Lysine plays an indispensable role in the functioning of our immune system. In addition, lysine can work together with other semi-essential amino acids to synthesize proteins, such as collagen, to keep our skin, hair and nails healthy.


Tryptophan is an aromatic amino acid that is characterized by the functionality of the indole group. It performs several functions in the body, especially the nervous system – the task of the chemical mediator. Unlike other amino acids, L-tryptophan is not soluble in water and it is sufficiently resistant to heat – in the process it is lost only in a small amount.For more visit
