As for the ester exchange reaction on phosphorus, it was found that N-phosphoryl histidine the fastest one among all of the N-phosphoryl aminoacids. The results studied by MNDO method indicate that due to theparticipation of imidazole group, the formation of hexa-coordinatephosphorus intermediate made the iso-propoxyl which is opposite toimidazole group more active than the other ones and much easier to leave.When iso-propoxyl left, a new penta-coordinate phosphorus intermediate wasformed, and it is sterically favorable to be attacked by an alcohol from theopposite direction of imidazole.

对于磷上酯交换反应，实验中发现N-磷酰组氨酸反应速度明显高于其它N-磷酰氨基酸，理论研究表明，侧键咪唑基参与下六配位磷中间体形成后，位于咪唑基对面的异丙氧基反应活性大大提高，即从咪唑基的对面位置发生异丙氧基的离去和另一分子醇的进攻，在能量上和空间上都是有利的。N-磷酰丝氨酸的磷上酯交换反应有着类似的特点。

Environmental factors also affect degradation rate, which will increase as temperature and moisture increased , Temperature effect coefficient varies from 1.08 to 1.42, which is not in accordance with Van't Hoff rule, and it is proved that the effect of temperature on degradative rate in soil is less than that in water.
