| Outline of Final Research Achievements |
The cell membrane, a separator for the interior of cells from the outside environment, is formed by lipids which are relative insoluble in water. Its lipid component is not uniform and changes in each small structural unit of the micro - nanometer scale to play key roles in the signal transduction and the mass transport across the cell membrane. Lipophilic compounds in vivo are not dissolvable in water, and are adsorbed on the surface of hydrophobic sites such as the cell membrane. Therefore, lipophilic compounds reacts with biomolecules in membrane bound structures rather than in aqueous solution structures. In this study, we succeeded in the quantification of the effect of the membrane lipid composition on the reaction between lipophilic compounds and soluble protein as free energy by using isothermal titration calorimetry.
