Metabolite Identification
Common NameGentisate aldehyde
DescriptionGentisate aldehyde belongs to the class of organic compounds known as hydroxybenzaldehydes. These are organic aromatic compounds containing a benzene ring carrying an aldehyde group and a hydroxyl group. Gentisate aldehyde exists in all living organisms, ranging from bacteria to humans. Gentisate aldehyde 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 gentisate aldehyde a potential biomarker for the consumption of these foods. Gentisate aldehyde 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 Gentisate aldehyde.
