It is well known that adenosine triphosphate (ATP) is an important biomolecule.It plays an essential role in the metabolism of living systems and is the prime energy source for numerous physiological processes.The hydrolysis of ATP to adenosine diphosphate (ADP) involves a free energy change of about--9 kcal/mole. Because of such a large energy resulting from the cleavage of P-O bond in ATP, the bond is call- 展开更多

Adenosine Triphosphate (ATP) is one of the most important biomolecules. It plays an essential role in hying systems and was extensively investigated by not only experimental methods but theoretical calculations as well. As early as 1960, Fukui et al and Pullman et al. studied the molecule through a simple molecular orbital method (H(?)ckel theory). Although H(?)ckel theory had been applied to ATP molecule, it did not give satisfactory resuhs, as the three-dimensional structure 展开更多
