Application

L-Arginine monohydrochloride has been used to study the effects of amino acids in promoting food consumption in Drosophila melanogaster. It has also been used to develop a non-invasive chronic pancreatitis model of rat.

Biochem/physiol Actions

L-Arginine is a semi-essential amino acid. This dibasic amino acid acts as a precursor for creatinine and is a natural constituent of most of the dietary proteins.
Substrate of nitric oxide synthase, which is converted to citrulline and nitric oxide (NO). Induces insulin release by a nitric oxide-dependent mechanism.
