Abstract The quenching reaction of hemoporphyrin with human serum albumin(HSA) was studied by using fluorescence spectra and absorption spectra.The formation constants of them were analyzed at different temperature according to Stern-Volmer equation and double-reciprocal equation, which are smaller at high temperature than at low temperature.The binding site was calculated (r=4.36) by Fster energy transfer mechanism, and the thermodynamic parameters were obtained.H-bond and Van der Waals are two main reactions between HP and HSA.
