Amino acids are the structural chemical units that make up proteins. Every living organism is made up of proteins. Various forms of proteins are involved in all processes occurring in living organisms. The body Rights of the proteins formed muscles, ligaments, tendons, all the organs and glands, hair, nails, whites are part of the fluid and bones. Enzymes and hormones that catalyze and regulate all the processes in the body, are also proteins. Deficiency of proteins in the body can lead to a breach of the water balance, causing swelling. Each protein in the body is unique and exists for a particular purpose.
Proteins are not interchangeable. They are synthesized in the body from amino acids, which result from breakdown of proteins, which are in food. Thus, it is amino acids, not proteins themselves are the most valuable. Apart from the fact that amino acids form the proteins that make up tissues and organs of the human body because some of them are: act as neurotransmitters or are their predecessors. Neurotransmitters – are chemicals that transmit nerve impulse from one nerve cell to another. Thus, some amino acids are essential for normal brain. Amino acids contribute to the fact that vitamins and minerals to adequately perform their function. Some amino acids directly supply the energy muscle.
Amino acids are divided into essential (valine, leucine, isoleucine, threonine, methionine, phenylalanine, tryptophan, lysine), partially interchangeable (Arginine and histidine) and nonessential (alanine, asparagine, aspartic acid, glycine (glycine), glutamine, glutamic acid, proline, serine, tyrosine, cysteine (cystine)). Essential amino acids are not synthesized in the body rights, but are necessary for normal life. They must be ingested with food. With a lack of essential amino acids is delayed growth and development of the organism. Optimal content of essential amino acids in dietary protein depends on age, sex and occupation rights, as well as from other causes. Nonessential amino acids are synthesized in the body.
