Metabolite Identification
Common NameHydroxybutyrylcarnitine
DescriptionHydroxybutyrylcarnitine, also known as C4OH Carnitine, is classified as a member of the acyl carnitines. Acyl carnitines are organic compounds containing a fatty acid with the carboxylic acid attached to carnitine through an ester bond. Hydroxybutyrylcarnitine is considered to be a slightly soluble (in water) and a weak acidic compound. Hydroxybutyrylcarnitine is a fatty ester lipid molecule. Hydroxybutyrylcarnitine can be found in blood. Within a cell, Hydroxybutyrylcarnitine is primarily located in the extracellular space and near the membrane.
