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 + Pialso requires approx. 30 kJ/moleof energy under standard conditions.*AMP + PiADP + H2OΔG°≈+ 30 kJ/moleDehydration rx.Consider the formation of ADPH2OAcid anhydride bond formation4
