Its achiral structure features fused five- and six-membered nitrogen-containing rings, a purine structure similar to that of adenosine. Synthesized in plants from xanthosine, it is extracted into supercritical carbon dioxide. It differs by a methyl group from the related compound theobromine, which is found in chocolate.
