Metabolite Identification

Common Name

4-Hydroxy-2-oxoglutaric acid

Description

4-Hydroxy-2-oxoglutaric acid, also known as 2-keto-4-hydroxyglutarate, 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. 4-Hydroxy-2-oxoglutaric acid exists in all living species, ranging from bacteria to plants to humans. In humans, 4-hydroxy-2-oxoglutaric acid is involved in the metabolic disorder called hyperornithinemia with gyrate atrophy (hoga). 4-Hydroxy-2-oxoglutaric acid has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make 4-hydroxy-2-oxoglutaric acid a potential biomarker for the consumption of these foods. 4-Hydroxy-2-oxoglutaric acid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on 4-Hydroxy-2-oxoglutaric acid.
