Sugar phosphates are defined as carbohydrates to which a phosphate group is bound by an ester or an either linkage, depending on whether it involves an alcoholic or a hemiacetalic hydroxyl, respectively. Deoxyribose is a modified form of another sugar called ribose. The result is a free-floating phosphate plus ADP, or adenosine diphosphate (meaning it only has two phosphate groups).
