Purine

Purine is a heterocyclic aromatic organic compound that consists of two rings (pyrimidine and imidazole) fused together. It is water-soluble.

Pyrimidinenoun

Pyrimidinenoun

any of several basic compounds derived from pyrimidine

Pyrimidinenoun

a heterocyclic organic compound with a penetrating odor

Pyrimidine

Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. One of the three diazines (six-membered heterocyclics with two nitrogen atoms in the ring), it has the nitrogen atoms at positions 1 and 3 in the ring.
