L-(+)Lysine Monohydrate is an amino acid essential to human nutrition, though not synthesized by the human body. It regulates calcium absorption, protein, enzyme, antibody, and hormone synthesis. It is used as a substrate for oxidation and glycation mechanism studies. L-lysine mainly participates in electrostatic interactions in proteins. It promotes calcium uptake, which is essential for carnitine production and collagen formation.
