Mixed monolayers of phospholipid and cholesterol have been studied at the air-water interface by means of surface pressure and surface potential measurements. Two synthetic phospholipids were used; di-stearoyl dl-α-phosphatidyl ethanolamine and di-myristoyl dl-α-phosphatidyl choline. Only the surface pressure results for the di-myristoyl dl-α-phosphatidyl chorine-cholesterol mixtures indicated significant deviations from ideal mixing. In addition, the surface potential results for this system indicated dipole shifts to have taken place on mixing and these data are analysed by two different methods. Published work on phospholipid-cholesterol mixed monolayers is discussed.
