ethanol treatment ( 1 min ) of pc and fg at 37 degrees c significantly increased the peak intensity of -ch3 groups in a dose-dependent manner , while no intensity change in pc and a lesser change in fg were observed for the +n ( ch3 ) 3 groups , suggesting a greater disorganizing effect of ethanol in the inner hydrophobic ( -ch3 ) compared with the outer hydrophilic [ +n ( ch3 ) 3 ] membrane moieties of phospholipids .
