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.
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 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).
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 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.
Guanosine monophosphate (GMP), also known as 5′-guanidylic acid or guanylic acid (conjugate base guanylate), is a nucleotide that is used as a monomer in RNA. It is an ester of phosphoric acid with the nucleoside guanosine. GMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase guanine; hence it is a ribonucleotide ...
So the next time you're thinking about grabbing a cold one, just remember that in the amount of time it takes you to finish the can, you're causing a lot more long-term damage than you think.
In enzymology, a deoxyguanosine kinase (EC 2.7.1.113) is an enzyme that catalyzes the chemical reaction ATP + deoxyguanosine ⇌ {\displaystyle \rightleftharpoons } ADP + dGMP Thus, the two substrates of this enzyme are ATP and deoxyguanosine , whereas its two products are ADP and dGMP .
