The effect of N-phosphoamino acids on plant cells'membrane permeability was investigated by osmotic method. It was found that in all N-phosphoamino acids, only some phosphoryl polar amino acids such as DIPPSer, DIPPThr, DIPPHis, DIPPAsp, DIPPGlu, DIPPAsn and free serine, threonine could increase the water permeability in plant cell membrane. For example, after 20min. treatment by 1. 5mM DIPPSer, the deplasmolysis time of onion cells was shortened 50%.

三、通过透性实验研究了N-磷酰化氨基酸对洋葱、豌豆等植物细胞膜水透性及溶质透性的影响，发现在所有的N-磷酰化氨基酸及自由氨基酸中，仅有部分N-磷酰极性氨基酸和自由的丝、苏氨酸对植物细胞膜上水透性有增强作用，如1.5mM N-磷酰化丝氨酸可使洋葱细胞质壁复原时间缩短一半以上。
