Adenosine triphosphate consists of the purine adenine linked through its N9 to d-ribose via a β-N-glycosidic C(1′) linkage; the α-phosphoryl group is linked via an ester linkage to the alcoholic O of ribose (C5′), and the β- and γ-phosphoryl groups form anhydride bonds. The chemical energy stored in the anhydride bonds is released upon hydrolysis at the γ- or β-phosphorus.
