Chemical Information
Name1-Methyluric acid
Description1-Methyluric acid, also known as 1-methylate, 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 a methyl group at N-1. 1-Methyluric acid is an extremely weak basic (essentially neutral) compound (based on its pKa). 1-Methyluric acid exists in all living organisms, ranging from bacteria to humans. 1-methyluric acid can be biosynthesized from 1-methylxanthine through the action of the enzyme xanthine dehydrogenase/oxidase. In humans, 1-methyluric acid is involved in caffeine metabolism.
