L-Alanine by MP Biomedicals is a high purity amino acid. This is an -amino acid which contains an -amino group, an -carboxylic acid group, and a side chain consisting of a 3-carbon aliphatic straight chain ending in a guanidino group. This preparation is available as a white powder which is soluble in water. This is a precursor for the biosynthesis of nitric oxide. It is synthesized from citrulline in arginine and proline metabolism, by the sequential action of the cytosolic enzymes, argininosuccinate synthetase (ASS) and argininosuccinate lyase (ASL). CAS No. 74-79-3 Quantity Provided: 25 gm per pack Molecular Formula: C6H14N4O2 Molecular Weight: 174.2 Soluble in water L-Alanine is widely used in chemical and biological sectors. Arginine plays a significant role in cell division, wound healing, removing ammonia from the body, immune function, and the release of hormones. As a precursor for the synthesis of nitric oxide, it is important in the regulation of blood pressure. Intravenously-administered arginine is used in growth hormone stimulation tests because it can stimulate the secretion of growth hormone. L-Arginine is used in cell culture as a component of MEM amino acids solution and in various culture media.
