Arginine can also be produced synthetically, and arginine-related compounds can be used in treating people with liver dysfunction due to its role in promoting liver regeneration. It can then be converted into nitric oxide by the human body, a chemical known to relax blood vessels.ĭue to its vasodilatory effects, arginine has been put forward for the treatment of people with chronic heart failure, high cholesterol, compromised circulation and high blood pressure, although research on these fronts is still ongoing. In humans, arginine is produced when proteins are digested. Only the l-stereoisomer participates in the biosynthesis of proteins.

Its low reactivity contributes to the simple, elongated structure of silk with few cross-links which gives the fibers strength, stretch resistance and flexibility. Discovered in protein in 1875, alanine makes up 30% of the residues in silk.
