| Cytosine Usage And Synthesis |
| Description | Cytosine is pyrimidine; along with adenine and guanine they account for the fi ve nucleic acid bases. Pyrimidines are heterocyclic single-ringed compounds based on the structure of pyrimidine. Cytosinelike adenine and guanine, form nucleosides and nucleotides in RNA and DNA. When the bases combine with ribose, a ribonucleoside forms; and when it attaches to deoxyribose, a deoxyribosenucleoside is formed. Names of the nucleoside are summarized in Table 29.1.these in turn combine with phosphoryl groups, in a process called phosphorylation, to form their respective nucleotides that form nucleic acids.the nucleotides can be tri, di, and mono phosphate nucleotides similar to the way in which adenine forms ATP, ADP, and AMP. |
| Chemical Properties | White Solid |
| History | Cytosine is first isolated by hydrolysis of calf thymus tissue by Albrecht Kossel (1853–1927) and A. Neumann during 1893–1894. Thymine’s structure was published in 1900 and confi rmed over the next several years when it was synthesized by several investigators. In 1903, cytosine was synthesized by Henry Lord Wheeler (1867–1914) and Treat B. Johnson, confirming its structure. Uracil was first isolated in 1900 from yeast nucleic acid found in bovine thymus and herring sperm.the methylation of uracil produces thymine; thymine is also called 5-methyluracil because methylation takes place at the fi fth carbon in uracil to produce thymine. |
| Uses | Cytosine is a nucleoside used for proteomics research. It is also used as an enzyme substrate or precursor of effector molecules such as cytosine sugars. |
| Uses | Cytosine has been used:
|
| Uses | Widely distributed in nature; constituent of nucleic acids |
| Definition | ChEBI: An aminopyrimidine that is pyrimidin-2-one having the amino group located at position 4. |
