Amino acids or alpha-amino acids (H2NCHRCOOH) are molecules that contain amine and carboxyl functional groups and vary in size from a hydrogen atom in glycine through a methyl group in alanine to a large heterocyclic group in tryptophan. Besides the natural amino acids, there is a wide range of non-natural amino acids that can be availed from us. Extensively used in technology and chemical industries, these amino acids are formulated with precision for ensuring safety in application.
