For Research Use OnlyL - Carnitine
L-carnitine is a quaternary ammonium compound involved in the transport of fatty acids across the mitochondrial membrane, where they become available for beta-oxidation. Supplied at 500mg per vial. It is not a peptide, and a certificate describing it in peptide terms indicates analysis performed from a template rather than against what the material actually is; the appropriate characterisation is that of a small molecule. Like other compounds that participate stoichiometrically rather than by signalling, it is supplied in hundreds of milligrams rather than single digits, which is a consequence of how it works and not a measure of potency. Research use only.
