CAS 71-30-7 Cytosine Pyrimidines 4-AMINO-2(1H)-PYRIMIDINONE

Description

Cytosine, or 2-carbonyl - 4-aminopyrimidine, is one of the four basic bases that make up DNA. Cytosine nucleoside and cytosine nucleotide can be used as drugs to raise leukocyte. It can be synthesized from dimercaptoacil, concentrated ammonia and chloroacetic acid

Basic Parameters

Structural formula

What is the role of the cytosine?

Cytosine plays an essential role in forming base pairs by bonding with guanine and forming the genetic code found in both DNA and RNA. Because of its chemical structure, cytosine represents a nucleotide base due to its ability to bond with guanine and form part of the sugar-phosphate backbone of DNA and RNA

What is the cytosine in DNA?

Cytosine (C) is one of the four nucleotide bases in DNA, with the other three being adenine (A), guanine (G) and thymine (T). Within a double-stranded DNA molecule, cytosine bases on one strand pair with guanine bases on the opposite strand. The sequence of the four nucleotide bases encodes DNA's information.

What makes up cytosine?

Cytosine is a pyrimidine nucleobase with a chemical formula of C4H5N3O. Pyrimidine is a heterocyclic aromatic organic compound with a single ring (called a pyrimidine ring) with alternating carbon and nitrogen atoms. Cytosine has a molar mass of 111.10 g/mol and a melting point of 320 to 325 °C

How much of DNA is cytosine?

Cytosine (C) makes up 42% of the nucleotides in a sample of DNA from an organism.

What is the other name for cytosine?

The other names for cytosine are 2-oxy-4-aminopyrimidine and 4-amino-2(1H)-pyrimidinone. It has a chemical formula of C4H5N3O and a molecular weight of 111.10 atomic mass units. Cytosine was first discovered in 1894 when it was isolated from calf thymus tissues.

Why is cytosine called cytosine?

After German Cytosin, equivalent to Ancient Greek κύτος (kútos) + -ine. Cytosine was discovered and named by the German biochemists Albrecht Kossel and Albert Neumann in 1894 when it was hydrolyzed from calf thymus tissues.
