Regulatory evidence across markets

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

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.

Palmitoyl Carnitine

O-palmitoyl-L-carnitine is an O-acyl-L-carnitine in which the acyl group is specified as palmitoyl (hexadecanoyl). It has a role as an EC 3.6.3.9 (Na(+)/K(+)-transporting ATPase) inhibitor, a mouse metabolite and a human metabolite. It is a saturated fatty acyl-L-carnitine, a long-chain fatty acyl-L-carnitine and an O-palmitoylcarnitine. It is functionally related to a hexadecanoic acid. — ChEBI
