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

	Figure 1. Structure of ATP. The purine base, adenine, is linked to d-ribose by a –N-glycosidic bond. The 5¢ position of ribose is linked by an ester bond to P, which in turn is linked by an anhydride bond to P and P of a pyrophosphate moiety.
	Figure 2. The processes that synthesize and utilize ATP.
	Figure 3. A schematic representation of ATP synthase. The F₁ component (₃₃) is arranged in a flattened sphere of alternating and subunits. Together with the subunit, which anchors the c subunits, the rotatory motor is formed with the subunit as the drive shaft. F₁ is further connected to F₀, which is responsible for proton translocation, by a stalk consisting of the subunits and b₂.
