A pyrimidine is an organic ring consisting of six atoms: 4 carbon atoms and 2 nitrogen atoms. The nitrogen atoms are placed in the 1 and 3 positions around the ring. Atoms or groups attached to this ring distinguish pyrimidines, which include cytosine, thymine, uracil, thiamine (vitamin B1), uric acid, and … See more A purine contains a pyrimidine ring fused with an imidazole ring (a five-member ring with two non-adjacent nitrogen atoms). This two-ringed structure has nine atoms forming the ring: 5 carbon atoms and 4 nitrogen atoms. … See more While purines and pyrimidines include molecules that are active on their own (as in drugs and vitamins), they also form hydrogen … See more The purines and pyrimidines both consist of heterocyclic rings. Together, the two sets of compounds make up the nitrogenous bases. … See more WebDespite a diet that may be rich in nucleoproteins, dietary purines and pyrimidines are not incorporated directly into tissue nucleic acids. Humans synthesize the nucleic acids and their derivatives ATP, NAD +, coenzyme A, etc, from amphibolic intermediates.However, injected purine or pyrimidine analogs, including potential anticancer drugs, may nevertheless be …

WebJul 25, 2024 · Pyrimidine: Definition. Pyrimidines have a six-member nitrogen-containing ring, like purines, but no corresponding five-nitrogen ring. These compounds therefore have a longer name but are smaller and lighter in the physical world. Pyrimidine bases in DNA include cytosine and thymine; pyrimidines in RNA include cytosine and uracil.
