Application

L-Arginine monohydrochloride has been used to study the reversal of the inhibitory effect of L-NG0-nitroarginine on non-cholinergic relaxations. It has also been used as a dietary supplement to study its effect on endothelium-dependent vasodilation.

Biochem/physiol Actions

L-Arginine is considered as a semi essential amino acid. In most mammals including humans, L-Arginine synthesis occurs through intestinal-renal axis, from glutamine, glutamate and proline. Abnormal levels of L-Arginine is associated with the development of kidney and cardiovascular disease. L-arginine is found to decrease fat mass and visceral adiposity.
Substrate of nitric oxide synthase, which is converted to citrulline and nitric oxide (NO). Induces insulin release by a nitric oxide-dependent mechanism.
