- Pyrimidine - Wikipedia
Pyrimidine (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) [3] 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 Difference Between Purines and Pyrimidines - ThoughtCo
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- Definition, Properties, Structure, Uses - Microbe Notes
Pyrimidine is a cyclic organic compound with a ring of 6 atoms; four carbon atoms with attached hydrogen or side chain and 2 nitrogen atoms at -1, and -3 positions The carbon (C) and nitrogen (N) atoms are bonded by single and double bonds altering each other
- Pyrimidine - The Definitive Guide - Biology Dictionary
Pyrimidine is a simple aromatic ring composed of two nitrogen atoms and four carbon atoms, with hydrogen atoms attached to each carbon The carbon and nitrogen atoms are connected via alternating double and single bonds
- Purines and Pyrimidines - Science Notes and Projects
Pyrimidines consist of a single six-membered ring with two nitrogen atoms and four carbon atoms The general molecular formula for pyrimidines is C 4 H 4 N 2 Cytosine (both DNA and RNA), thymine (in DNA), and uracil (in RNA) are the primary pyrimidines Like purines, pyrimidines also contribute to the structure of DNA and RNA
