Abstract

An approximate, new model for the structure of the periodic, undulated P(beta'), phase of phosphatidylcholine bilayers is proposed. The properties of this phase are deduced by minimizing a Landau-de Gennes expression for the bilayer free energy when this free energy contains a term favoring a spontaneous curvature of the membrane. The theoretical calculation leads to a model for the P(beta') phase of phosphatidylcholine bilayers having a number of novel physical properties, including periodic variations in membrane "fluidity."

摘要

提出了一个关于周期性波纹 P(beta') 相磷脂双层结构的近似新模型。当双层自由能包含一个有利于膜自发曲率的项时,通过最小化 Landau-de Gennes 对双层自由能的表达式来推导出这个相的性质。理论计算得出了一个具有许多新物理性质的磷脂酰胆碱双层 P(beta') 相模型,包括膜“流动性”的周期性变化。
