摘 要:The fluorescence of gramicidin A(GA) in lipid bilayer may be quenched by Hypocre-Ilin 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’ pho-toinduced electron theory, and an electron transfer inverted region hypothesis is proposed,
