Regulatory evidence across markets

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

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.

L-Lysine

L-lysine is an L-alpha-amino acid; the L-isomer of lysine. It has a role as a micronutrient, an anticonvulsant, a nutraceutical, a mouse metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite, an Escherichia coli metabolite, a human metabolite and an algal metabolite. It is a L-alpha-amino acid, an aspartate family amino acid, a lysine and a proteinogenic amino acid. It is a conjugate base of a L-lysinium(1+). It is a conjugate acid of a L-lysinate. It is an enantiomer of a D-lysine. It is a tautomer of a L-lysine zwitterion and a L-Lysine zwitterion. — ChEBI
