Also known as 2-amino-9-beta-D-ribofuranosyl-1,9-dihydro-6H-purin-6-one, Guanosin, Guo, 2(3H)-imino-9-beta-D-ribofuranosyl-9H-purin-6(1H)-one, Guanine-9-beta-D-ribofuranoside, Guanine riboside, 9-beta-D-ribofuranosyl-guanine, 2-amino-1,9-dihydro-9-beta-D-ribofuranosyl-6H-purin-6-one
Guanosine (symbol G or Guo) is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N9-glycosidic bond. Guanosine can be phosphorylated to become guanosine monophosphate (GMP), cyclic guanosine monophosphate (cGMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP). These forms play important roles in various biochemical processes such as synthesis of nucleic acids and proteins, photosynthesis, muscle contraction, and intracellular signal transduction (cGMP). When guanine is attached by its N9 nitrogen to the C1 carbon of a deoxyribose ring it is

グアノシン〈Guanosine〉はグアニンにリボース環がβ-N9-グリコシド結合で構成されたヌクレオシドである。 グアノシンはリン酸化されてGMP〈グアニル酸〉、cGMP〈環状グアノシン一リン酸〉、GDP〈グアノシン二リン酸〉そしてGTP〈グアノシン三リン酸〉 グアニンがデオキシリボース環に結合したものが、デオキシグアノシンと呼ばれる。
