Metabolite Identification
Common Name1-Methylhypoxanthine
Description1-Methylhypoxanthine belongs to the class of organic compounds known as hypoxanthines. Hypoxanthines are compounds containing the purine derivative 1H-purin-6(9H)-one. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. 1-Methylhypoxanthine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 1-Methylhypoxanthine.
