Metabolite Identification
Common NameButyrylcarnitine
DescriptionButyrylcarnitine, also known as O-butanoylcarnitine, 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, butyrylcarnitine is considered to be a fatty ester lipid molecule. Butyrylcarnitine is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Butyrylcarnitine exists in all eukaryotes, ranging from yeast to humans. Butyrylcarnitine is a potentially toxic compound. Butyrylcarnitine has been found to be associated with several diseases known as obesity, eosinophilic esophagitis, and pregnancy; also butyrylcarnitine has been linked to several inborn metabolic disorders including short chain acyl-coa dehydrogenase deficiency and very long chain acyl-coa dehydrogenase deficiency.
