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]]. ==External links== {{Nucleobases, nucleosides, and nucleotides}} [[Category:Nucleosides]] {{biochem-stub}} [[es:Guanosina]] [[fr:Guanosine]] [[it:Guanosina]] [[lt:Guanozinas]] [[ja:グアノシン]] [[pt:Guanosina]] [[zh:鳥苷]]
