Metabolite Identification
Common Name5-Hydroxymethyl-4-methyluracil
Description5-Hydroxymethyl-4-methyluracil, also known as pentoxyl or 4-methyl-5-hydroxymethyluracil, belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-Hydroxymethyl-4-methyluracil 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 5-hydroxymethyl-4-methyluracil a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 5-Hydroxymethyl-4-methyluracil.
