Orientation of Molecules at Oil-Water Interfaces

Fig. 47. Comparison of proposed structure of primary and secondary bile salt micelles and a classical detergent micelle (43). (A, C) Longitudinal and cross sections of primary and secondary bile salt micelles, respectively. (B) Ordinary detergent micelles. Top— Orientation of molecules at oil-water interface (refer to Section V). Wavy line—Hydrocarbon chains of detergent molecules. Shaded area—Lipidsoluble cyclic hydrocarbon part of bile salt molecule. Polar head of detergent molecule. OH or ester groups. Negatively charged ionic group of bile salt.
