The Biological Significance of Plasma Membrane Physical Properties

Abstract

Plasma membrane can be considered as a protector surrounding materials inside a biology cell from the outsiders. The backbone of the plasma membrane is a lipid bilayer. The lipid bilayer composes of various lipid molecules, and every single molecule owns their unique physical properties. The interaction among various lipid molecules and between the molecules and their aqueous environment determines the physical behaviour of lipid molecules in membrane. Some important physical behaviours are: fluidity of the membrane, permeability of the membrane, and mechanical strength of the membrane. In this talk, I will describe what biological meanings of these physical behaviours of the plasma membranes.
