That describes this inventory, not the law. No imported rule is not evidence that an ingredient is permitted: a rule may exist under another name or identifier, or in a dataset not yet imported here.
Chemical identity and properties
DL-Arginine
Arginine is an alpha-amino acid that is glycine in which the alpha-is substituted by a 3-guanidinopropyl group. It has a role as a fundamental metabolite. It is a member of guanidines, a polar amino acid and an alpha-amino acid. It contains a 3-carbamimidamidopropyl group. It is a conjugate base of an argininium(1+). It is a conjugate acid of an argininate. — ChEBI
