Metabolite Identification
Common NameOxoglutaric acid
DescriptionOxoglutaric acid, also known as oxoglutarate or alpha-ketoglutarate, belongs to the class of organic compounds known as gamma-keto acids and derivatives. These are organic compounds containing an aldehyde substituted with a keto group on the C4 carbon atom. Oxoglutaric acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Oxoglutaric acid exists in all living species, ranging from bacteria to humans. Oxoglutaric acid is a potentially toxic compound. Oxoglutaric acid has been found to be associated with several diseases known as schizophrenia, eosinophilic esophagitis, amish lethal microcephaly, and anoxia; also oxoglutaric acid has been linked to the inborn metabolic disorders including d-2-hydroxyglutaric aciduria.
