L-lysine is an essential amino acid in animals and humans. L-Lysine is necessary for protein synthesis in the body and proper growth. L-lysine lowers the cholesterol level by producing carnitine. L-lysine aids in calcium, zinc and iron absorption. Athletes take L-lysine as a supplement for lean mass building and for proper muscle and bone health. L-lysine competes with arginine during viral replication and reduces herpes simplex virus infection. L-lysine supplementation reduces chronic anxiety in human. Lysine reduces viscosity of serum albumin solution for injections. | [Purification Methods]
Likely impurities are arginine, D-lysine, 2,6-diaminoheptanedioic acid and glutamic acid. Crystallise the monohydrochloride from water at pH 4-6 by adding 4 volumes of EtOH. At above 60% relative humidity it forms a dihydrate. [Birhbaum et al. J Biol Chem 194 455, 468 1952, Kearley & Ingersoll J Am Chem Soc 73 5783 1951, Beilstein 4 IV 2717.] |
