Metabolite Identification
Common NameImidazolone
DescriptionImidazolone belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. In humans, imidazolone is involved in the histidine metabolism pathway. Imidazolone 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 imidazolone a potential biomarker for the consumption of these foods. Imidazolone 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 Imidazolone.
