Metabolite Identification
Common Name2-dehydropantoate
Description2-dehydropantoic acid, also known as ketopantoate, belongs to short-chain keto acids and derivatives class of compounds. Those are keto acids with an alkyl chain the contains less than 6 carbon atoms. 2-dehydropantoic acid is soluble (in water) and a weakly acidic compound (based on its pKa). 2-dehydropantoic acid can be found in a number of food items such as radish (variety), red algae, cherimoya, and avocado, which makes 2-dehydropantoic acid a potential biomarker for the consumption of these food products. 2-dehydropantoic acid exists in E.coli (prokaryote) and yeast (eukaryote).
