Metabolite Identification
Common NameIsovaleryl-L-carnitine
DescriptionIsovaleryl-L-carnitine, also known as 3-methylbutyrylcarnitine, 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, isovaleryl-L-carnitine is considered to be a fatty ester lipid molecule. Isovaleryl-L-carnitine is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
