Metabolite Identification
Common Name3-Oxohexanoic acid
Description3-Oxohexanoic acid, also known as 3-oxohexanoate, belongs to the class of organic compounds known as medium-chain keto acids and derivatives. These are keto acids with a 6 to 12 carbon atoms long side chain. 3-Oxohexanoic acid exists in all eukaryotes, ranging from yeast to plants to humans. In humans, 3-oxohexanoic acid is involved in the fatty acid biosynthesis pathway. 3-Oxohexanoic 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 3-oxohexanoic acid a potential biomarker for the consumption of these foods. 3-Oxohexanoic 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 a significant number of articles have been published on 3-Oxohexanoic acid.
