L-Arginine is one of the three amino acids with basic side chains, and is very hydrophilic in character. It contains a guanidino group in the side chain, and this moiety is protonated at physiological pH.
Arginine is biosynthesized in the kidneys from citrulline, whose precursor is glutamate via the formation of ornithine. In amino acid degradation in vivo, arginine is hydrolyzed to urea and ornithine by arginase. Arginine can be metabolized to glutamate, which in turn is converted to α-ketoglutarate for entry into the citric acid cycle.
L-Arginine plays an important role in cell division, the healing of wounds, removing ammonia from the body, immune function, and the release of hormones. It is used as a precursor for the synthesis of nitric oxide (NO), reduces healing time of injuries (particularly bone), quickens repair time of damaged tissue and decreases blood pressure.
Substrate of nitric oxide synthase, which is converted to citrulline and nitric oxide (NO). Induces insulin release by a nitric oxide-dependent mechanism.
Soluble in water (50 mg/ml).
