Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name O-PHOSPHOSERINE.

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.

Phospho-L-serine

O-phospho-L-serine is the L-enantiomer of O-phosphoserine. It has a role as an EC 1.4.7.1 [glutamate synthase (ferredoxin)] inhibitor, a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, an EC 2.5.1.49 (O-acetylhomoserine aminocarboxypropyltransferase) inhibitor, an EC 4.3.1.10 (serine-sulfate ammonia-lyase) inhibitor and a human metabolite. It is a conjugate acid of an O-phosphonato-L-serine(2-). It is an enantiomer of an O-phospho-D-serine. — ChEBI
