[Extraction of lipoprotein components with emulsions]

Extraction of lipoprotein components from water solutions by means of emulsions similar to "water in oil" was studied, where either suspension of glycosides in buffer or water solution of diethyl ether and ethanol were used as an inner phase of the emulsion. The first type of extraction enabled to isolate selectively free cholesterol from lipoproteins and the second type--lipids, respectively. The rate of cholesterol isolation from lipoproteins of various classes, dependent on the strength of cholesterol binding in lipoproteins was increased as follows: alpha less than beta less than pre-beta-lipoproteins; the procedure allowed to isolate selectively cholesterol from atherogenous lipoproteins.
