Amino Acid Analysis Protein
Biosyn provides amino acids analysis service. Using ion exchange, post-column Ninhydrin detection, we provide precise determination of protein quantities, but also provide detailed information regarding the relative amino acid composition that gives a characteristic protein profile, which is often sufficient for identification of a protein.
An Essential Amino Acid
An essential amino acid or indispensable amino acid is an amino acid that cannot be synthesized de novo by the organism and therefore must be supplied in the diet. Nine amino acids are generally regarded as essential for humans: phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, histidine, leucine, and lysine. Arginine is required by infants and growing kids.
Essential Amino Acids
Amino Acids are the chemical units or "building blocks" of the body that make up proteins. Protein substances make up the muscles, tendons, organs, glands, nails, and hair. Growth, repair and maintenance of all cells are dependent upon them.
In chemistry, an amino acid is a molecule containing both amine and carboxyl functional groups. In biochemistry, this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent. In the alpha amino acids, the amino and carboxylate groups are attached to the same carbon, which is called the α–carbon. The various alpha amino acids differ in which side chain (R group) is attached to their alpha carbon.
