WebMar 27, 2024 · 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 barbituates. WebCytosine is of the four bases in DNA and RNA with the function of cytosine being controlling of the hereditary material for the living cells and also in some serving as a coenzyme that shall act in conjunction with the enzymes in body. The bases can be a derivative of both pyrimidine and purine.

"Cytosine can be found as part of DNA, as part of RNA, or as a part of a nucleotide. As cytidine triphosphate (CTP), it can act as a co-factor to enzymes, and can transfer a phosphate to convert adenosine diphosphate (ADP) to adenosine triphosphate (ATP). In DNA and RNA, cytosine is paired with guanine. However, it is … See more Cytosine (symbol C or Cyt) is one of the four nucleobases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents … See more Cytosine was discovered and named by Albrecht Kossel and Albert Neumann in 1894 when it was hydrolyzed from calf thymus tissues. A structure was proposed in 1903, and was synthesized (and thus confirmed) in the laboratory in the same year. See more • Cytosine MS Spectrum • EINECS number 200-749-5 • Shapiro R (1999).
