Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name ARGININE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

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

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. — ChEBI
