Regulatory evidence across markets

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

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-Phenylalanine

L-phenylalanine is the L-enantiomer of phenylalanine. It has a role as a micronutrient, a nutraceutical, an EC 3.1.3.1 (alkaline phosphatase) inhibitor, a mouse metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite, a human xenobiotic metabolite, an Escherichia coli metabolite and an algal metabolite. It is a L-alpha-amino acid, a phenylalanine, an erythrose 4-phosphate/phosphoenolpyruvate family amino acid and a proteinogenic amino acid. It is a conjugate base of a L-phenylalaninium. It is a conjugate acid of a L-phenylalaninate. It is an enantiomer of a D-phenylalanine. It is a tautomer of a L-phenylalanine zwitterion. — ChEBI
