The Structure of Liquid Crystal and Solubilization of Cholesterol in Lecithin-Water-Oleic Acid System
Formation and structure of liquid crystal in lecithin-water-oleic acid system were studied. It was found that different from the lecithin-water system, there are two types of liquid crystal present. The lamellar liquid crystal was formed at lower content of oleic acid, the values of interlayer spacing are larger than the values in the corresponding liquid crystal without oleic acid. The inverse hexan nal liquid crysta1 was formed at higher content of oleic acid. In lecithin-water-oleic acid(containing 15℅ cholesterol) system the phase behavior of liquid crystal is similar to that in the lecithin-water-oleic acid system. The solubilization rate of solid cholesterol in lamellar liquid crystal of lecithin-water-oleic acid system is more faster than that of lecithin-water system.
