Metabolite Identification
Common NameL-Carnitine
DescriptionL-Carnitine, also known as carnitine d-form, belongs to the class of organic compounds known as carnitines. These are organic compounds containing the quaternary ammonium compound carnitine. L-Carnitine is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). L-Carnitine participates in a number of enzymatic reactions, within cattle. In particular, Propionyl-CoA and L-carnitine can be converted into propionylcarnitine through its interaction with the enzyme carnitine O-acetyltransferase. In addition, Acetyl-CoA and L-carnitine can be converted into L-acetylcarnitine through its interaction with the enzyme carnitine O-acetyltransferase. In cattle, L-carnitine is involved in the metabolic pathway called the oxidation OF branched-chain fatty acids pathway.
