arginine

(är`jənĭn), organic compound, one of the 20 amino acidsamino acid
, any one of a class of simple organic compounds containing carbon, hydrogen, oxygen, nitrogen, and in certain cases sulfur. These compounds are the building blocks of proteins.

 commonly found in animal proteins. Only the l-stereoisomer participates in the biosynthesis of proteins. Its basic side chain adds a positive charge and hence a greater degree of water-solubility to proteins in neutral solution. Although arginine can be synthesized from cellular metabolites, it is usually considered essential to the diet of children for the maintenance of normal rates of growth. Arginine is the direct metabolic precursor of ureaurea
, organic compound that is the principal end product of nitrogen metabolism in most mammals. Urea was the first animal metabolite to be isolated in crystalline form; its crystallization was described in the early 18th cent.

, the dominant nitrogenous waste product of most mammals. It was discovered in protein in 1895.
