| Abstract: | The interaction mechanism and mode of glycitein（GL）with bovine serum albumin（BSA） in pH 7.4 PBS was studied by fluorescence spectroscopy.The intrinsic fluorescence of BSA could be quenched by GL.Further more,the numbers of binding site were 1.30 and 1.73 while the apparent binding constants were 8.09×104L·mol-1 and 5.22×104L·mol-1 at 310K and 315K,respectively.The thermodynamic parameters had indicated that the type of force was hydrogen bonding and Van-der Waals force.Synchronous fluorescence spectra showed that the structure of BSA was changed when GL was added.The method could be significant for understanding the interaction mechanism between GL and proteins. |
