Deoxyguanosine

Deoxyguanosine is a nucleosides containing guanine. Deoxyguanosine differs from guanine in containing a sugar (deoxyribose). Phosphorylation of deoxyadenosine produces a nucleotide found in DNA.

Guanosine is a related nucleoside that contains Ribose instead of deoxyribose as the sugar.
