【Abstract】 The distribution of Ag + in gelatin with respect to molecular weight was studied using gel exclusion chromatography―flame atomic a bsorption spectroscopy. Firstly, several gels used for isolating gelatin protein components were studied and the result indicated that dextran G 75 was favoura ble for the present study. The γ, β, α and other lower molecular weight compo nents of gelatin could be isolated from each other by means of gel G 75. The re sults demonstrated that the Ag + in gelatin was combined only with the α prote in component and not with the γ or the β components. [WT5HZ更多还原
