Pyrimidine - Wikipedia
WebPyrimidine (C 4 H 4 N 2; / p ɪ ˈ r ɪ. m ɪ ˌ d iː n, p aɪ ˈ r ɪ. m ɪ ˌ d iː n /) is an aromatic, heterocyclic, organic compound similar to pyridine (C 5 H 5 N). 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.

WebMar 27, 2019 · Purines and pyrimidines are two types of aromatic heterocyclic organic compounds. In other words, they are ring structures (aromatic) that contain nitrogen as well as carbon in the rings (heterocyclic). Both purines and pyrimidines are similar to the chemical structure of the organic molecule pyridine (C 5 H 5 N).
Pyrimidine metabolism - Wikipedia
WebPyrimidine catabolism. Pyrimidines are ultimately catabolized (degraded) to CO 2, H 2 O, and urea. Cytosine can be broken down to uracil, which can be further broken down to N-carbamoyl-β-alanine, and then to beta-alanine, CO 2, and ammonia by beta-ureidopropionase.
