Chemical Information
FooDB Name3,7-Dimethyluric acid
Description3,7-Dimethyluric acid, also known as 3,7-dimethylate or 3,7-DMU, belongs to the class of organic compounds known as xanthines. These are purine derivatives with a ketone group conjugated at carbons 2 and 6 of the purine moiety. An oxopurine that is 7,9-dihydro-1H-purine-2,6,8(3H)-trione substituted by methyl groups at N-3 and N-7. 3,7-Dimethyluric acid is an extremely weak basic (essentially neutral) compound (based on its pKa). 3,7-Dimethyluric acid exists in all living organisms, ranging from bacteria to humans. 3,7-dimethyluric acid can be biosynthesized from theobromine through the action of the enzyme xanthine dehydrogenase/oxidase. In humans, 3,7-dimethyluric acid is involved in caffeine metabolism.
