Phospholipids are amphiphilic molecules. Such molecules consist of two parts — one easily soluble in water (the so-called polar head) and the other highly insoluble, composed of two aliphatic chains (see Figure la). When put into water, these molecules organize themselves so as to minimize their free energy, building up structures such as a spherical bilayer, called a vesicle (see Figure lb). There has been considerable interest in studying such structures, in part because they represent a somewhat idealized model of a biological membrane. In addition, and from a more practical point of view, they are considered as potential drugs carriers which could eventually deliver their content to special body regions where membrane permeability would be altered, by a slight change in temperature, for example.
