Dictionary » G » Guanosine




A purine nucleoside that has guanine bound to a ribose sugar.


Guanosine may become guanosine monophosphate (GMP), guanosine diphosphate (GDP) or guanosine triphosphate (GTP) through phosphorylation.

Word origin: guano- from guanine + ribo- from ribose + -ine.

Molecular formula: C10H13N5O5

Synonym: guanine riboside.
Compare: deoxyguanosine.
See also: nucleoside.

... size. It is similar to restriction mapping. However, the bases do not need to be known. Dimethylsulfate is used to determine purines (G and A). Guanosine is affected more than Adenosine and gel bands appear darker on a gel. Hydrazine works for pyrimidines (C and T). Only Cystine bases are cleaved ...

ATP and GTP..what's the difference?

... agree that BioChem is put inside the molecular bio I wanna ask something. What are the differences between ATP (Adhenosine triphospate) and GTP (Guanosine triphosphate)? is there any different function of these two?
