Metabolite Identification
Common NameMesoxalic acid
DescriptionMesoxalic acid, also known as ketomalonic acid or a-ketomalonate, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. Mesoxalic acid has been detected, but not quantified in, several different foods, such as breakfast cereal, cereals and cereal products, common peas (Pisum sativum), and herbs and spices. This could make mesoxalic acid a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Mesoxalic acid.
