膜中弹性耦合插入物的有效弹性常数

Effective spring constants for the elastically coupled insertions in membranes

Yury S. Neustadt, Michael B. Partenskii

摘要:

在线弹性理论中,由夹杂物(例如,脂质双层中的跨膜肽)可以严格地以耦合谐振子的形式存在。对于相当一般的边界条件,这里导出相应的“有效弹性常数“的一般表达式,例如,对于接触斜率的方位角变化。两个插入的情况下被认为是在更详细的。

英文摘要:

In linear elastic theory, membrane deformation energy caused by inclusions (e.g., membrane-spanning peptides in lipid bilayers) can be rigorously presented in terms of coupled harmonic oscillators. The general expressions for the corresponding "effective spring constants" are derived here for quite general boundary conditions allowing, e.g., for the azimuthal variation of the contact slope. The case of two insertions is considered in more details.
