Metabolite Identification
Common Name3-Mercaptolactic acid
Description3-Mercaptolactic acid, also known as 3-mercaptolactate, belongs to the class of organic compounds known as monosaccharides. Monosaccharides are compounds containing one carbohydrate unit not glycosidically linked to another such unit, and no set of two or more glycosidically linked carbohydrate units. Monosaccharides have the general formula CnH2nOn. In humans, 3-mercaptolactic acid is involved in the cysteine metabolism pathway. 3-Mercaptolactic 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 3-mercaptolactic acid a potential biomarker for the consumption of these foods. 3-Mercaptolactic 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 very few articles have been published on 3-Mercaptolactic acid.
