Detailed explanation-1: -An ATP molecule consists of three parts (Fig. 1.7): adenine (a double ring of carbon and nitrogen), ribose sugar (five-carbon sugar), and three phosphate groups attached to ribose, which are linked by covalent bonds.
Detailed explanation-2: -The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups. ATP is commonly referred to as the “energy currency” of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.
Detailed explanation-3: -The molecule consists of three components: an adenine bicyclic system, a furanose ring, and a triphosphate chain. Two research groups reported the discovery of ATP in 1929.
Detailed explanation-4: -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.
