3D structure of ATP

ATP (adenosine triphosphate) has a compact 3D shape composed of three main parts: an adenine base (a nitrogen-rich ring), a ribose sugar (a five-carbon sugar), and three phosphate groups linked in a chain. The adenine and ribose form a structure called adenosine, while the phosphate groups extend from the sugar, creating a tightly packed molecule. The arrangement allows energy stored in the high-energy bonds between the phosphates to be efficiently released during cellular processes, fueling functions like muscle contraction, signaling, and biosynthesis. Its 3D shape is crucial for its ability to interact with enzymes and other molecules.
