The mechanism of action was proved to be reversible phosphorylation and dephosphorylation.

其理亦是通过可逆磷酸化及脱磷酸化进行。

Novel phosvitin phosphopeptides (PPP) were prepared by tryptic hydrolysis following alkaline dephosphorylation of hen egg yolk phosvitin.

以卵黄高磷蛋白质为原料,经碱法脱磷、胰蛋白酶分离制备得到一种新型卵黄高磷蛋白磷酸肽(PPP)。
