a purine nucleoside that has guanine linked by its n9 nitrogen to the c1 carbon of ribose. it is a component of ribonucleic acid and its nucleotides play important roles in metabolism. (from dorland, 28th ed) Guanosine is a nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a beta-N9-glycosidic bond. Guanosine can be phosphorylated to become GMP (guanosine monophosphate), cGMP (cyclic guanosine monophosphate), GDP (guanosine diphosphate) and GTP (guanosine triphosphate). (Wikipedia); The nucleoside guanosine exert important neuroprotective and neuromodulator roles in the central nervous system, which may be related to inhibition of the glutamatergic neurotransmission activity. Guanosine is the specific extracellular guanine-based purines effector and indicate that its conversion occurs not only in the central nervous system but also peripherally. (PMID: 16325434); Guanosine is a nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a ?-N9-glycosidic bond.
