Description and Uses
Guanosine is a purine nucleoside that is comprised of the purine base guanine attached to a ribose moiety. Mono-, di-, tri-, and cyclic monophosphorylated forms of guanosine (GMP, GDP, GTP, and cGMP, respectively) are essential for a variety of endogenous biochemical processes, such as signal transduction, metabolism, and RNA synthesis.
Guanosine has been used:
- as a reference standard for the analysis of glucosinolates by high-performance liquid chromatography with diode-array detection and electrospray ionization tandem mass spectrometry (HPLC-DAD-ESI/MS)
- as a component of Mouse Embryonic Fibroblasts (MEFs) culture
- as a standard for the detection of residual RNA contaminant in oil palm plant genome samples by HPLC
