| Abstract: | The fluorescence of gramicidin A(GA) in lipid bilayer may be quenched by Hypocrellin B. When the phospholipids undergo a phase transition from gel to liquid crystalline phase, the reaction rate decreases unusually. This phenomenon has been analyzed by Marcus’ photoinduced electron theory, and an electron transfer inverted region hypothesis is proposed, which may adequately explain this abnormal phenomenon. |
