基于Monte Carlo的含脂质运动的单分子膜模拟方法

Method for the Monte Carlo based Simulation of Lipid-Monolayers including Lipid Movement

J. Griesbauer, A. Wixforth, H. M. Seeger, M. F. Schneider

摘要:

本文用一个由六角连接的有序或无序状态的脂质组成的两态模型建立了单分子膜的蒙特卡罗模拟。脂质的连接通过牛顿弹簧实现,该牛顿弹簧模拟表面弹性并允许计算脂质的平移运动,而所有必要的模拟参数都来自实验。模拟的单层等温线可以直接比较,同时允许测量的计算实验上很难访问的单层热容。

英文摘要:

A two-state-model consisting of hexagonally connected lipids being either in the ordered or disordered state is used to set up a Monte Carlo Simulation for lipid monolayers. The connection of the lipids is realized by Newtonian springs emulating the surfaces elasticity and allowing for the calculation of translational movement of the lipids, whereas all necessary simulation parameters follow from experiments. Simulated monolayer isotherms can be directly compared to measured ones concurrently allowing the calculation of the experimentally hardly accessible monolayer heat capacity.
