NCIt definition : The hydrochloride salt form of arginine, an essential amino acid in juvenile humans.
Arginine is a complex amino acid, often found at active sites in proteins and enzymes
due to its amine-containing side chain. Arginine may prevent or treat heart and circulatory
diseases, combat fatigue, and stimulate the immune system. It also boosts production
of nitric oxide, relaxing blood vessels, and treating angina and other cardiovascular
problems. Arginine is also an important intermediate in the urea cycle and in detoxification
of nitrogenous wastes. (NCI04);
