“…In Fig. 3, the MIP values of the present bilayers are plotted against the acyl chain length together with the previous results [32][33][34][35]. The MIP values of the CnPC bilayers decreased with an increase in acyl chain length in a smooth non-linear manner.…”

“…The MIP values of the CnPC bilayers decreased with an increase in acyl chain length in a smooth non-linear manner. Recently, we have demonstrated that the C22PC bilayer forms the L ␤ I phase by only hydration under atmospheric pressure by SANS under atmospheric pressure and fluorometry under high pressure [35]. We expected in this study that the C21PC bilayer may be the longest chain PC that requires pressure to induce bilayer interdigitation.…”

“…In all CnPC bilayers except the C22PC bilayer ( Fig. S3) [35], the L ␤ I phase was induced in the high-pressure region in between the L ␤ and P ␤ phases.

“…The thermodynamic quantities of phase transitions for the present CnPC bilayers under atmospheric pressure are summarized in Table 1 together with those of the C18PC [32] and C22PC bilayers [35]. Here the entropy changes ( S) were calculated from the equation of S = H/T using the H and T values from DSC, and the V values were from the Clapeyron equation using the H values and the dT/dp values from the T-p curves of the phase boundary [32].…”

“…From the acyl chain-length dependence of the MIP values, it is expected that in the bilayer of certain CnPC with longer acyl chains the enhanced interaction may induce the bilayer interdigitation under atmospheric pressure by only hydration. Previously we demonstrated this on the T-p phase diagram of the dibehenoyl-PC (C22PC) bilayer by methods of small angle neutron scattering (SANS) and fluorometry [35]. At the same time, it was suggested that the dihenearachidoyl-PC (C21PC) is the longest chain CnPC that requires pressure to induce the bilayer interdigitation.…”

Bilayers formed by phospholipids are fundamental structures of biological membranes. The mechanical perturbation brought about by pressure significantly affects the membrane states of phospholipid bilayers. In this chapter, we focus our attention on the pressure responsivity for bilayers of some major phospholipids contained in biological membranes. At first, the membrane states and phase transitions of phospholipid bilayers depending on water content, temperature and pressure are explained by using the bilayer phase diagrams of dipalmitoylphosphatidylcholine (DPPC), which is the most familiar phospholipid in model membrane studies. Subsequently, the thermotropic and barotropic bilayer phase behavior of various kinds of phospholipids with different molecular structures is discussed from the comparison of their temperature--pressure phase diagrams to that of the DPPC bilayer. It turns out that a slight change in the molecular structure of the phospholipids produces a significant difference in the bilayer phase behavior. The systematic pressure studies on the phase behavior of the phospholipid bilayers reveal not only the pressure responsivity for the bilayers but also the role and meaning of several important phospholipids existing in real biological membranes.
