Effect of cholesterol on 16:0 LacCer, 18:0 LacCer, and 24:0 LacCer interfacial behavior. The surface pressure versus average cross-sectional molecular area (π-A) isotherms and the surface compressional modulus versus average cross-sectional molecular area (Cs−1-A) responses are shown for 16:0 LacCer/cholesterol (A and D), 18:0 LacCer/cholesterol (B and E), and 24:0 LacCer/cholesterol (C and F), respectively. Data were collected at 24°C. Isotherms (from right to left at 5 mN/m) contain 0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6 mol fraction of cholesterol. Matching line styles in the upper and lower panels indicate equivalent cholesterol content.
