Detailed explanation-1: -ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.

Detailed explanation-2: -ATP is composed of an adenine ring, ribose sugar, and three phosphate groups (triphosphate). The groups of the phosphate group are usually called the alpha (), beta (), and gamma () phosphates.

Detailed explanation-3: -ATP Structure and Function ATP (adenosine triphosphate) has three phosphate groups that can be removed by hydrolysis to form ADP (adenosine diphosphate) or AMP (adenosine monophosphate). If there are no phosphates at all, the molecule is referred to as a “nucleoside", rather than a “nucleotide".

Detailed explanation-4: -The primary phosphate group on the ATP molecule that is hydrolyzed when energy is needed to drive anabolic reactions is the -phosphate group. Located the farthest from the ribose sugar, it has a higher energy of hydrolysis than either the -or -phosphate.
