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.

guanosine monophosphate

(mŏn′ō-fŏs′fāt′)
n.
GMP.

guanosine monophosphate (GMP)

a nucleotide that plays an important role in various metabolic reactions and in the formation of RNA from DNA templates.

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.
