Decoupling of crystalline and conformational degrees of freedom in lipid monolayers

摘要: A theoretical study is performed on a microscopic interaction model which describes the transitions between liquid and solid phases of lipid monolayers spread air/water interfaces. The accounts for condensation in terms acyl‐chain conformational degrees freedom as well variables describe orientations crystalline domains solid. phase behavior function temperature lateral pressure explored using mean‐field theory computer‐simulation techniques. Attention paid to particular interplay two types processes effects due decoupling order parameters. In case decoupling, predicts that high‐pressure solid‐conformationally ordered separated from low‐pressure liquid‐conformationally disordered by phase. This prediction consistent with synchrotron x‐ray experiment...
