Perez, Hugo A. published the artcileEffect of cholesterol on the surface polarity and hydration of lipid interphases as measured by Laurdan fluorescence: New insights, Product Details of C8H18O, the main research area is cholesterol dipalmitoylphosphatidylcholine Laurdan fluorescence spectroscopy; Cholesterol; Laurdan fluorescence; Lipid membranes; Organic solvents.
Comparison of the behavior of Laurdan in gel and in the liquidcrystalline DPPC bilayers with that observedin chloroform and OctOH allow concluding that changes in the membrane lipid order cannot be ascribed to changes in viscosity of the local environment. Cholesterol acts as a spacer below the transition temperatureof DPPC, promoting a disorder state in the acyl chain region. No evidence of water entrance has been detected with Laurdan up to 30% Cholesterol in DPPC in this condition. In contrast, Chol displaces to longer values the wavelength of Laurdan in membranes in the liquidcrystallinestate. This decrease in polarity occurs above 5% Chol and is directly related to the water extrusion produced by Chol. This effect is similar to that occurring in liquid crystalline membranes subjected to hypertonic stress. The behavior is comparable to that of Laurdan in OctOH at different water ratios below 5% Chol/DPPC. At higher ratios, other changes are evident.
