Related to guanosine: guanosine monophosphate

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

guan·o·sine (G, Guo),

(gwahn'ō-sēn, -sin),
9-β-d-ribosylguanine (guanine combined through its N-9 with the C-1 of β-d-ribose); a major constituent of RNA and of guanine nucleotides.

guanosine

/gua·no·sine/ (gwah´no-sēn) a purine nucleoside, guanine linked to ribose; it is a component of RNA and its nucleotides are important in metabolism. Symbol G.
cyclic guanosine monophosphate  3′,5′-GMP, cGMP, cyclic GMP; a cyclic nucleotide that acts as a second messenger similar in action to cyclic adenosine monophosphate but generally producing opposite effects on cell function.

guanosine

(gwä′nə-sēn′, -sĭn)
n.
A nucleoside, C10H13N5O5, consisting of guanine and ribose.

guanosine

[gwan′ōsēn]
a nucleoside composed of guanine and a sugar, d-ribose. It is a major component of the nucleotides guanosine monophosphate and guanosine triphosphate and of RNA. A related nucleoside, deoxyguanosine, is a major component of DNA.

A major constituent of RNA and of guanine nucleotides.

guanosine (gwän´əsēn),

n a compound derived from a nucleic acid, composed of guanine and a sugar, D-ribose. Guanosine is a major molecular component of the nucleotides guanosine monophosphate and guanosine triphosphate and of DNA and RNA.
guanosine triphosphate (GTP),
n a high-energy nucleotide, similar to adenosine triphosphate, that functions in various metabolic reactions such as the activation of fatty acids and the formation of the peptide bond in protein synthesis.

guanosine

a nucleoside, guanine riboside, one of the major constituents of nucleic acids.

cyclic guanosine monophosphate (cyclic GMP, cGMP)
a cyclic 3′,5′-phosphate that acts as an intercellular second messenger mediating the activity of hormones and other substances; essential in vision where cGMP concentrations increase in the dark.
guanosine monophosphate
a nucleotide important in metabolism and nucleic acid synthesis; called also GMP.
guanosine pentophosphate
involved with guanosinetetraphosphate in the so called stringent response of bacteria in which, because the cell does not have a sufficient pool of amino acids to maintain protein synthesis, tRNA and rRNA synthesis is reduced by about 20-fold, which suspends many of the cells' activities until conditions improve.
guanosine tetraphosphate
see guanosine pentophosphate (above).
guanosine triphosphate
an energy-rich compound involved in several metabolic reactions; called also GTP.
