pyrimidine
Sign in to savePyrimidine (; ) 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 nitrogen atoms at positions 1 and 3 in the ring. The other diazines are pyrazine (nitrogen atoms at the 1 and 4 positions) and pyridazine (nitrogen atoms at the 1 and 2 positions).
AI overview
Pyrimidine is a six-sided ring-shaped molecule made of carbon and hydrogen atoms with two nitrogen atoms positioned opposite each other, and it belongs to a small family of similar compounds called diazines. It's an important building block in nature, particularly in the molecules that make up DNA and RNA, which carry genetic information in all living things.

Pyrimidine (; ) is an aromatic, heterocyclic, organic compound similar to pyridine ().

The other diazines are pyrazine (nitrogen atoms at the 1 and 4 positions) and pyridazine (nitrogen atoms at the 1 and 2 positions).
In nucleic acids, three types of nucleobases are pyrimidine derivatives: cytosine (C), thymine (T), and uracil (U).
