Metabolite Identification
Common NameDiacetyl
DescriptionDiacetyl, also known as 2,3-butadione or dimethylglyoxal, belongs to the class of organic compounds known as alpha-diketones. These are organic compounds containing two ketone groups on two adjacent carbon atoms. Thus, diacetyl is considered to be an oxygenated hydrocarbon lipid molecule. Diacetyl exists as a liquid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Diacetyl exists in all living species, ranging from bacteria to humans. Diacetyl is a potentially toxic compound. Diacetyl has been found to be associated with several diseases known as ulcerative colitis, nonalcoholic fatty liver disease, and crohn's disease; also diacetyl has been linked to the inborn metabolic disorders including celiac disease.
