Deoxyguanosine is composed of the purine nucleobase guanine linked by its N9 nitrogen to the C1 carbon of deoxyribose. It is similar to guanosine, but with one hydroxyl group removed from the 2' position of the ribose sugar (making it deoxyribose). If a phosphate group is attached at the 5' position, it becomes deoxyguanosine monophosphate.
Guanosine (symbol G or Guo) is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N 9-glycosidic bond.Guanosine can be phosphorylated to become guanosine monophosphate (GMP), cyclic guanosine monophosphate (cGMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP).
Deoxyguanosine monophosphate (dGMP), also known as deoxyguanylic acid or deoxyguanylate in its conjugate acid and conjugate base forms, respectively, is a derivative of the common nucleotide guanosine triphosphate (GTP), in which the –OH group on the 2' carbon on the nucleotide's pentose has been reduced to just a hydrogen atom (hence the "deoxy-" part of the name).
8-Oxo-2'-deoxyguanosine (8-oxo-dG) is an oxidized derivative of deoxyguanosine. 8-Oxo-dG is one of the major products of DNA oxidation . [ 1 ] Concentrations of 8-oxo-dG within a cell are a measurement of oxidative stress .
Deoxyguanosine diphosphate (dGDP) is a nucleoside diphosphate. It is related to the common nucleic acid guanosine triphosphate (GTP), with the -OH group on the 2' carbon on the nucleotide's pentose removed (hence the deoxy- part of the name), and with one fewer phosphoryl group than GTP.
Two experiments conducted by Levy et al. showed that heating 10 mol·L −1 NH 4 CN at 80 °C for 24 hours gave a yield of 0.0007%, while using 0.1 mol·L −1 NH 4 CN frozen at −20 °C for 25 years gave a 0.0035% yield. These results indicate guanine could arise in frozen regions of the primitive earth.

Deoxyguanosine triphosphate [1] (dGTP) is a nucleoside triphosphate, and a nucleotide precursor used in cells for DNA synthesis. The substance is used in the polymerase chain reaction technique, in sequencing, and in cloning. It is also the competitor of inhibition onset by acyclovir in the treatment of HSV virus. [2]
