L-Arginine Structure

Synonyms: (S)-2-Amino-5-guanidinopentanoic acid, L-Arg, Arg, (S)-2-Amino-5-[(aminoiminomethyl)amino]pentanoic acid

L-Arginine is a conditionally essential amino acid that serves as a key precursor to nitric oxide, creatine, and polyamines. Produced via microbial fermentation and purified to high purity, it meets USP/EP/AJI standards for pharmaceutical and nutraceutical use.

As a versatile raw material, L-Arginine is widely employed in sports nutrition, cardiovascular health supplements, wound healing formulations, and parenteral nutrition. Its ability to support vasodilation and protein synthesis makes it a staple in both clinical and consumer health products.
