Guanosine

Guanosine is a purine nucleoside.

Chemical Formula: C₁₀H₁₇N₅O₇

Other names: 2-Amino-1,9-dihydro-9-beta-D-ribofuranosyl-6H-purin-6-one

Layman's explanation: Guanosine is formed when guanine attaches to the sugar ribose to form a glycosidic linkage. It is involved with the direct preservation and transfer of chemical energy in living systems. Guanosine is present in every cell in the human body. Guanosine is a purine, meaning that it is a single ring structure. A carbon sugar ring attaches to nitrogen in the base to form an N-glycosylic bond. The nitrogenous bases, which are primarily nonpolar, pack tightly enough to exclude water and form a stable, primarily nonpolar environment in the helix interior.

Keywords: nitrogenous base, nonpolar, purine
