%0 Journal Article %T Abnormal behavior of fluorescence quenching of gramicidin A in phase transition of lipid vesicles by hypocrellin B¡ªDoes an electron transfer inverted region exist? %A Jiachang Yue %A Yeping Li %A Yaxian Su %A Kechun Lin %J Chinese Science Bulletin %@ 1861-9541 %D 1999 %I %R 10.1007/BF02887123 %X 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. %K fluorescence quenching %K hypocrellin B %K Marcus theory %U http://link.springer.com/article/10.1007/BF02887123
