Adenine Chemical Properties,Uses,Production

Description

adenine is one of the purine nitrogenous bases that composes DNA and RNA; composed of two carbon–nitrogen rings. Adenine bonds with thymine in DNA and with uracil in RNA (see base pairing rule); it is also a major component of other molecules such as adenosine triphosphate.

Chemical Properties

White to almost white crystalline powder

Physical properties

Adenine is a white crystalline substance that is an important biological compound found in deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and adenosine triphosphate (ATP). It was once commonly referred to as vitamin B4 but is no longer considered a vitamin. Adenine is derived from purine. Purine is a heterocyclic compound.

History

Adenine is one of the two purines found in DNA and RNA. The other is guanine. Adenine and guanine are called bases in reference to DNA and RNA. A nucleic acid base attached to ribose forms a ribonucleoside. Adenine combined with ribose produces the nucleoside adenosine.

Uses

local antiseptic

Uses

Vitamin B4

Uses

Widespread throughout animal and plant tissues combined with niacinamide, d-ribose, and phosphoric acids; a constituent of nucleic acids and coenzymes, such as codehydrase I and II, adenylic acid, coa laninedehydrase. It is used in microbial determination of niacin; in research on heredity, virus diseases, and cancer.

Uses

enteric coating

Uses

A purine nucleobase and a component of DNA

Definition

A nitrogenous base found in DNA and RNA. It is also a constituent of certain coenzymes and when combined with the sugar ribose it forms the nucleoside adenosine found in AMP, ADP, and ATP. Adenine has a purine ring structure.

Definition

adenine: A purine derivative. It isone of the major component bases ofnucleotides and the nucleic acidsDNA and RNA.

Definition

ChEBI: The parent compound of the 6-aminopurines, composed of a purine having an amino group at C-6.

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion. An experimental teratogen. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx,.

Purification Methods

Crystallise adenine from distilled water. [Beilstein 26 III/IV 3561.]
