guanosine

 [gwah´no-sēn]
a nucleoside, guanine riboside, one of the major constituents of RNA.
cyclic guanosine monophosphate a cyclic nucleotide, guanosine 3′,5′-cyclic monophosphate, an intracellular “second messenger” similar in action to cyclic adenosine monophosphate; the two cyclic nucleotides activate different protein kinases and usually produce opposite effects on cell function. Abbreviated 3′,5′-GMP, cGMP, and cyclic GMP.

guanosine triphosphate (GTP) a nucleotide required for RNA synthesis and involved in energy metabolism.
