Nageli and Cramer in 1855 had already suggested that biological cells are separated from their environment by a membrane possessing special characteristics, and in 1900 Overton performed some simple but classical experiments which proposed that cell membranes were composed of lipids (1).
1. Cell membranes are based on lipid bilayer. Plasma membranes consist of a lipid bilayer with proteins embedded in the bilayer. The principle lipids are phospholipids. A phospholipid molecules has a hydrophilic head with a phosphate group as part of its structure and two hydrophobic tails.The hydrophobic tails consist of long hydrocarbon chains..
