Metabolite Identification

Common Name

2-Methyl-4-oxopentanedioic acid

Description

2-Methyl-4-oxopentanedioic acid 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. 2-Methyl-4-oxopentanedioic acid has been detected, but not quantified in, fruits. This could make 2-methyl-4-oxopentanedioic acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methyl-4-oxopentanedioic acid.
