Deoxyguanosine is a nucleoside consisting of the base guanine and the sugar deoxyribose. It is like guanosine but with one oxygen atom removed. It is a nucleoside component of DNA. Deoxyguanosine can be converted to 8-hydroxy-deoxyguanosine (8-OHdG) due to hydroxyl radical attack at the C8 of guanine.

It is an organic compound with fomular C20H22O7.
