These days we hear a lot about amino acids. But many of us probably do not understand how they work or their link to human As is popularly known, different amino acids are the main components that makes up proteins.
Amino acids constitute a distinctive part of human body and What are Amino Acids? On this site, we use cookies to provide better service to our customers.

The amino acids are precisely these monomers or building blocks, carrying out an important role in the living organism's metabolism since amino acids are essential to keep the nitrogen balance and to promote growth.
Moreover, amino acids have a strong influence on the nutritive value of foods, as direct contributors to taste and as precursors of several compounds that are formed during preparation, storage and cooking. The proteins are hydrolysed into twenty different amino acids, nineteen of which are a a- amino acids - this means that the amino group NH 2 is bound to the carbon atom adjacent to the carboxyl group. The only exception to this general formula is proline since the NH 2 group is included in a five-carbon cyclic structure.
Every amino acid's name is abbreviated by a three-letter code - based on the first three letters of their names Fig. The specific side chain R of each amino acid affects their physical and chemical properties and, consequently, the properties of proteins. The essential amino acids are arginine required for the young, but not for adults , histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
These amino acids are required in the diet. Plants, of course, must be able to make all the amino acids. Humans, on the other hand, do not have all the the enzymes required for the biosynthesis of all of the amino acids.
Why learn these structures and properties? It is critical that all students of the life sciences know well the structure and chemistry of the amino acids and other building blocks of biological molecules. Otherwise, it is impossible to think or talk sensibly about proteins and enzymes, or the nucleic acids.
