title: Effects of farnesol on the thermotropic behavior of dimyristoylphosphatidylcholine.
abstract: Differential scanning calorimetry (DSC) and DPH fluorescence anisotropy have been used to investigate the effects of trans-trans farnesol on the physical properties of model membranes and extracted cell lipids. Farnesol was shown to have a significant effect on the gel to liquid-crystal phase transition temperature, the enthalpy of the transition and the transition co-operativity for extruded vesicles of dimyristoylphosphatidylcholine (DMPC). The phase transition of DMPC vesicles was eliminated at 25 mol% farnesol. Farnesol decreased the fluorescence anisotropy of the lipids extracted from human leukemia line CEM-C1 cells.
