Glycoside-membrane interactions and induction of hexagonal phases. a Turbidity increase upon addition of compounds 1 and 13 to LUVs of POPE at 35 °C. Results are given as a quotient between the absorbance of LUVs in the presence of glycoside minus its intrinsic absorbance (A–B) and the absorbance of LUVs in the presence of ethanol (A₀), thus expressing exclusively the changes in turbidity of LUVs caused by their interaction with glycosides. Results are expressed as mean ± SE (n = 3). b Steady-state fluorescence anisotropy of TMA-DPH in binary mixtures of POPE/Soy:PE 3:1 in the presence or absence of compounds 1 and 13 (50 μM). Each dot represents the mean of three replicates for control and compound 1 and five replicates for compound 13, expressed as mean ± SE
