L-Asparagine Monohydrate (H-Asn-OH·H2O) (CAS: 5794-13-8) is an organic compound, one of the 20 amino acids commonly found in animal Proteins. Only the l-stereoisomer participates in the biosynthesis of mammalian proteins. Its structure is identical to that of the amino acid aspartic acid, except that the latter compounds acidic side- chain carboxyl group has been coupled , yielding an amide. Like glutamine, asparagine is important in the metabolism of toxicin the body. L-Asparagine Monohydrate is used as food additives and pharmaceutical intermediates, nutritional supplement. It can also be used in biochemical research, manufacturing culture agents. Amino acids and peptide synthesis reagents.
