Molecular mechanism of interaction between resveratrol and trypsin by spectroscopy and molecular docking Molecular mechanism of interaction between resveratrol and trypsin was studied using fluorescence spectroscopy (intrinsic fluorescence, synchronous fluorescence, Three-dimensional fluorescence), ultraviolet-visible (UV-vis) spectroscopy, fourier transform infrared (FT-IR) spectroscopy and molecular docking method, as well as enzyme activity and antioxidant assay.
