Cytosine Chemical Properties,Uses,Production

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

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.

Definition

A nitrogenous base found in DNA and RNA. Cytosine has the pyrimidine ring structure.

Definition

cytosine: A pyrimidine derivative.It is one of the principal componentbases of nucleotides and the nucleicacids DNA and RNA.

Purification Methods

Cytosine crystallises from H2O as the monohydrate which loses water on heating above 100o. Its solubility in H2O is 0.77%. UV: max 267nm ( 6,100) in H2O pH 8.8 and 275nm ( 10,400) in 0.1N HCl.
