| Outline of Final Research Achievements |
Cholesterol is a major component of cell membranes and is thought to have an important role to play in the formation of microdomains called “lipid rafts” within the cell membrane. In this study, we investigated the phase behavior, relaxation behavior and mechanical behavior of cholesterol-phospholipid binary bilayer membranes (i.e., artificially-prepared model membranes) by means of various physicochemical techniques, including pressure perturbation calorimetry, to elucidate the structure of the cholesterol-induced microdomains within the binary bilayer and the formation mechanism of the microdomains.
