guanosine

[′gwän·ə‚sēn]
(biochemistry)
C10H13O5N5 Guanine riboside, a nucleoside composed of guanine and ribose. Also known as vernine.

Guanosine

 

the nucleoside consisting of the carbohydrate ribose and the nitrogen base guanine. Colorless crystals. Molecular weight, 283.26 and melting point. 235° C. Free guanosine is an intermediate product of metabolism. It is a component of nucleic acids and biologically active guanyl nucleotides, GMP, GDP. and GTP. GTP (guanosine triphosphate), an energy-rich phosphorus compound, is a coenzyme of some reactions, such as the amination of inosinic acid and the transference of amino acids to ribosomes during the biosynthesis of protein.
