Local:
Pyrimidine is a heterocyclic compound containing nitrogen atoms at positions 1 and 3 in six-membered ring structure molecule. The simplest one is Pyrimidine itself and the three major Pyrimidines in living systems are cytosine, thymine, and uracil. Pyrimidine and its derivatives are biologically important components of nucleic acids (DNA, RNA) and coenzymes. They can be the parent compound of many drugs, including the barbiturates.
