Purine is an organic compound made of carbon, hydrogen, and nitrogen. It has the chemical formula C5H4N4. Purine is a cyclic compound with two rings (a bicyclic compound). The rings share two atoms, so they are called fused. One of the rings is pyrimidine, and the other is imidazole. Because the rings have nitrogen, it is a heterocyclic compound.[1]

Purines are a family of chemicals where some of the hydrogen atoms are replaced by other functional groups. Purines are common in nature. Adenine and guanine, two of the four nucleobases that DNA is made of, are purines. The xanthines are a group of purines that includes caffeine and theobromine.
