Metabolite Identification
Common Name8-Oxoguanine
Description8-Oxoguanine belongs to the class of organic compounds known as purinones. These are purines in which the purine moiety bears a C=O group. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. 8-Oxoguanine 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 8-oxoguanine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 8-Oxoguanine.
