Summary Introduction

To analyse:

The reason why membrane containing cholesterol are stiff.

Introduction:

Cell membranes are primarily composed of phospholipids that have a charged phosphate head and an uncharged fatty acid tail. Phospholipids form bilayers in solution and retain a fluid structure. Cholesterol is a special type of lipid and belongs to the class of lipids called steroids. It is also a component of cell membranes and stabilizes the membranes.
