脂单分子层、双分子层和膜的一般模型

A generic model for lipid monolayers, bilayers, and membranes

F. Schmid, D. Duchs, O. Lenz, B. West

摘要:

我们描述了一个简单的粗粒度模型,适合于研究脂质层及其相变。脂质由具有亲溶剂性头部和疏溶剂性尾部组件的短半柔性珠链建模。他们被迫自组装成双分子层的计算便宜的“幻影溶剂”的环境。该模型再现了单层和双层最重要的相和相变。技术问题,如蒙特卡罗并行化方案进行了简要讨论。

英文摘要:

We describe a simple coarse-grained model which is suited to study lipid layers and their phase transitions. Lipids are modeled by short semiflexible chains of beads with a solvophilic head and a solvophobic tail component. They are forced to self-assemble into bilayers by a computationally cheap `phantom solvent' environment. The model reproduces the most important phases and phase transitions of monolayers and bilayers. Technical issues such as Monte Carlo parallelization schemes are briefly discussed.
