摘要: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."
