Abstract
The lateral diffusion coefficients of some ubiquinone homologues have been measured in phospholipid vesicles exploiting the fluorescence quenching of the probe 12‐(9‐anthroyl)stearate by the quinones. Diffusion coefficients higher than 10−6cm2 · s−1 have been found at 25°C, compatible with the localization of the ubiquinones in the low‐viscosity midplane region of the bilayer.Keywords
