A white, crystalline compound, C5H4N4, from which is derived a group of compounds including uric acid, xanthine, and caffeine. Or a purine derivative, especially the bases ad â¦ enine and guanine, which are fundamental constituents of nucleic acids.
Purines include adenine, guanine, hypoxanthine, xanthine, and caffeine. The first four purines, in combination with pyramidines, make up the genetic codes DNA and RNA, and energy molecules, such as ATP, GTP and coenzyme A. They are essential for life and are found in all plant and animal cells.
