[Spectroscopic studies on the self-association mechanism of biomembrane lipid components and their interaction with water and alcohols in a non-polar medium].
Main thermodynamic and spectral parameters are determined for dimers of cholesterol, water and complexes of lecithin with cholesterol, 7-dehydrocholesterol (7-DHC) and other donors of proton.  On the basis of analysis of the obtained quantitative data, a conclusion is drawn on a comparative contribution of certain functional groups of lecithin to the entalpy and entropy values with inermolecular interaction with cholesterol, 7-DHC and other hydroxyl-containing compounds.  A decrease in mobility of water molecules evidences for a configuration stability of lecithin complexes with water...
