Adenine vs. Purine

Adenine (A, Ade) is a nucleobase (a purine derivative). It is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The three others are guanine, cytosine and thymine.

Purine is a heterocyclic aromatic organic compound that consists of two rings (pyrimidine and imidazole) fused together. It is water-soluble.

A purine base, C5H5N5, that is the constituent involved in base pairing with thymine in DNA and with uracil in RNA.

a colourless crystalline compound with basic properties, forming uric acid on oxidation.

A base, C₅H₅N₅, found in certain glands and tissues, which pairs with thymine in DNA and uracil in RNA.

A double-ringed, crystalline organic base, C5H4N4, that is the parent compound of a large group of biologically important compounds.

(biochemistry) purine base found in DNA and RNA; pairs with thymine in DNA and with uracil in RNA

Any of a group of substituted derivatives of purine, including the nitrogen bases adenine and guanine, which are components of nucleic acids. Uric acid, caffeine, theobromine, and theophylline are also purines.

(organic compound) Any of a class of organic heterocyclic compounds, composed of fused pyrimidine and imidazole rings, that constitute one of the two groups of organic nitrogenous bases (the other being the pyrimidines) and are components of nucleic acids.

any of several bases that are derivatives of purine

a colorless crystalline nitrogen-containing organic base; the parent compound of various biologically important substances
