DescriptionGuanosine is a purine nucleoside. It is formed by a molecule of guanine attached to a ribose sugar molecule. Guanosine is the RNA nucleoside G. 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.
