3-Methyladenine
3-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). 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: EC 3.2.2.21) [HMDB]. 3-Methyladenine is found in many foods, some of which are sacred lotus, evergreen huckleberry, swamp cabbage, and red rice.

1H-imidazole-1-propanoic acid
An imidazolyl carboxylic acid that is propanoic acid in which one of the methyl hydrogens is substituted by an imidazol-1-yl group. It is a metabolite of histidine found in human urine and faeces.
3-methyladenine
A methyladenine that is adenine substituted with a methyl group at position N-3.
