Metabolite Identification
Common NameStearoylcarnitine
DescriptionStearoylcarnitine, also known as acylcarnitine C18:0, belongs to the class of organic compounds known as acyl carnitines. These are organic compounds containing a fatty acid with the carboxylic acid attached to carnitine through an ester bond. Thus, stearoylcarnitine is considered to be a fatty ester lipid molecule. Stearoylcarnitine is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. In cattle, stearoylcarnitine is involved in the metabolic pathway called the mitochondrial Beta-oxidation OF long chain saturated fatty acids pathway.
