'''Guanosine''' is a [[nucleoside]] comprising [[guanine]] attached to a [[ribose]] ([[ribofuranose]]) ring via a β-N<sub>9</sub>-[[glycosidic bond]].
Guanosine can be phosphorylated to become GMP ([[guanosine monophosphate]]), cGMP ([[cyclic guanosine monophosphate]]), GDP ([[guanosine diphosphate]]) and GTP ([[guanosine triphosphate]]).
When [[guanine]] is attached to a [[deoxyribose]] ring, it is known as a [[deoxyguanosine]].
