Guanosine - Wikipedia
Guanosine (symbol G or Guo) is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N 9-glycosidic bond. Guanosine can be phosphorylated to become guanosine monophosphate (GMP), cyclic guanosine monophosphate (cGMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP).

Guanosine | C10H13N5O5 | CID 135398635 - PubChem
Guanosine is a purine nucleoside in which guanine is attached to ribofuranose via a beta-N(9)-glycosidic bond. It has a role as a fundamental metabolite. It is a purines D-ribonucleoside and a member of guanosines. It is functionally related to a guanine.
Guanosine - an overview | ScienceDirect Topics
Guanosine is a purine nucleoside that acts as a natural regulator of glutamatergic excitotoxicity. It has been found to protect against neurotoxicity and promote neuroprotection in various models. Guanosine modulates glutamate transporter activity and prevents seizures and cell death by activating specific signaling pathways.
Guanosine Definition and Examples - Biology Online Dictionary
2021年1月20日 · Guanosine is a nucleoside consisting of guanine and ribose sugar linked by β-N 9-glycosidic bond. When a phosphate group is covalently attached to the sugar, it forms a nucleotide. An example of a nucleotide wherein three phosphate groups are attached to guanosine is guanosine triphosphate (GTP), one of the building blocks of RNA synthesis.

Guanosine and its role in neuropathologies - Purinergic Signalling
2016年3月22日 · Guanosine is a purine nucleoside thought to have neuroprotective properties. It is released in the brain under physiological conditions and even more during pathological events, reducing neuroinflammation, oxidative stress, and excitotoxicity, as well as exerting trophic effects in neuronal and glial cells.
Guanosine triphosphate Definition and Examples - Biology Online
2023年5月29日 · Guanosine triphosphate (GTP) (chemical formula: C 10 H 16 N 5 O 14 P 3) is a nucleoside phosphate comprised of a ribonucleoside and three phosphate groups. It means it has a ribose as its sugar and three phosphate groups attached.
Guanosine monophosphate Definition and Examples - Biology …
2021年7月21日 · Guanosine monophosphate (GMP) is a nucleoside phosphate in being comprised of a ribonucleoside and one phosphate group. It means, it has a ribose as its sugar and one phosphate group attached. Its nucleoside (called guanosine ) is made up of a purine base, i.e. a guanine, attached to the ribose sugar.
