Metabolite Identification
Common Name3-Methyladenine
Description3-Methyladenine, also known as 3-ma nucleobase, belongs to the class of organic compounds known as 6-aminopurines. These are purines that carry an amino group at position 6. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. 3-Methyladenine exists in all living species, ranging from bacteria to humans. 3-Methyladenine has been detected, but not quantified, in several different foods, such as soft-necked garlics, chinese bayberries, burbots, amaranths, and tea. This could make 3-methyladenine a potential biomarker for the consumption of these foods. 3-Methyladenine is one of the purines damaged by alkylation and oxidation which can be recognized and excised by the human 3-methyladenine DNA glycosylase (AAG) (EC: EC3.2.2.21).
