Beschreibung

Guanosine is a purine nucleoside that is comprised of the purine base guanine attached to a ribose moiety. Mono-, di-, tri-, and cyclic monophosphorylated forms of guanosine (GMP, GDP, GTP, and cGMP, respectively) are essential for a variety of endogenous biochemical processes, such as signal transduction, metabolism, and RNA synthesis.

Chemische Eigenschaften

White, crystalline powder; odorless; mild saline taste. Very slightly soluble in cold water; soluble in boiling water, dilute mineral acids, hot acetic acid, and dilute bases; insoluble in alcohol, ether, chloroform, and benzene.

Verwenden

Guanosine is used as a constituent of nucleic acids. It is used in metallic paints, simulated pearls,plastics,cosmetics industry etc,. It has been also used in pharmacokinetics as a prodrug. Guanosine is used in cell culture applications as a precursor of GMP.

Definition

ChEBI: A purine nucleoside in which guanine is attached to ribofuranose via a beta-N9-glycosidic bond.

Allgemeine Beschreibung

Guanosine is an aromatic organic molecule and a purine nucleoside. It is present in the cerebrospinal fluid, intestinal cells, blood-brain barrier and in brain microvessels.

l?uterung methode

It crystallises from water as a dihydrate. Dry it at 110o.[Beilstein 26/18 V 81.]
