What is "deoxyguanosine"

n. (context biochemistry English) A deoxyribonucleoside related to guanosine

n. a nucleoside component of DNA; composed of guanine and deoxyribose [syn: guanosine]

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.
