Guanosine is a nucleoside and consists of the nucleobase guanine and the sugar β- D- ribose .
Presentation and extraction
As a component of the ribonucleic acids, it can be made from these z. B. obtained in yeast.
properties
Guanosine is part of ribonucleic acid (RNA) and forms a base pair there with cytidine . The analogue with deoxyribose is deoxyguanosine .
Guanosine is part of the compounds GTP , GDP , of nucleic acids ( RNA , DNA - here the sugar ribose is replaced by deoxyribose ) and also a signaling molecule.
The compound is in the form of a dihydrate , which releases the water of crystallization from 110 ° C.
