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.
In addition to adenine and guanine, a group of chemical compounds called purine base include hypoxanthine (6-oxypurine), xanthine (2,6-dioxypurine), uric acid (2,6,8-trioxypurine), and theobromine (3,7-dimethyl xanthine). Theophylline and caffeine are a member of methylated purine family. Adenosine Triphosphate (ATP) : a nucleotide composed of adenine, the sugar ribose, and three phosphate groups; involved in energy metabolism and required for RNA synthesis.
