What is L-Arginine?
L-arginine is an L-alpha-amino acid that is the L-isomer of arginine. It has a role as a micronutrient, a nutraceutical, a biomarker, a mouse metabolite and an Escherichia coli metabolite. It is a L-alpha-amino acid, a glutamine family amino acid, an arginine and a proteinogenic amino acid. It is a conjugate base of a L-argininium(1+). It is a conjugate acid of a L-argininate. It is an enantiomer of a D-arginine.
