The formation of a acid anhydride bond from two phosphoric acid functional groups in a dehydration reaction under standard conditions requires an input of approximately 30 kJ/mole of energy, twice the amount of energy that is required in the formation of an ester bond. The formation of ATP from ADP + P i also requires approx. 30 kJ/mole of energy under standard conditions. * AMP + P i ADP + H 2 O Δ + 30 kJ/mole Dehydration rx. Consider the formation of ADP H 2 O Acid anhydride bond formation 4
