摘要

我们对疏水性脂链的构象多样性进行了研究。研究确定了脂质链可能的构象数量，以及这些构象在实际系统中可以实现的数量。提出了一种分析脂质分子构象的集合理论方法，并介绍了脂质结构中实现的构象集合与系统能量的关系。利用集合理论，研究了疏水性脂质链的哪些构象可以在实际系统中实现。提出了关键构象的概念，以估算脂质结构特征与膜能量特征之间的相关性。

Conformational Diversity of Lipids

The conformational diversity of hydrophobic lipid chains has been studied. The number of possible conformations of a lipid chain, as well as the number of these conformations that can be realized in a real system, has been determined. A set theory approach to the analysis of conformations of lipid molecules has been proposed, and a relation of the sets of conformations realized in a lipid structure to the energy of the system has been introduced. Using the set theory, it has been considered which conformations of hydrophobic lipid chains can be realized in the real system. The notion of the key conformation has been formulated to estimate the correlation between the structural characteristics of lipids and the energy characteristics of membranes.
