Metabolite Identification
Common NamePhenylglyoxylic acid
DescriptionPhenylglyoxylic acid, also known as benzoylformate or 2-oxo-2-phenylacetate, belongs to the class of organic compounds known as benzoyl derivatives. These are organic compounds containing an acyl moiety of benzoic acid with the formula (C6H5CO-). Phenylglyoxylic acid exists in all living organisms, ranging from bacteria to humans. Phenylglyoxylic 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 phenylglyoxylic acid a potential biomarker for the consumption of these foods. Phenylglyoxylic 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 Phenylglyoxylic acid.
