| Abstract: | In order to clarify effects of pressure on phospholipids, small-angle neutron scattering and X-ray scattering experiments on an aqueous solution of dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC) with small amount of ethanol were carried out. At moderate temperature and pressure (41 less than or equal to T less than or equal to 60 degreesC and 10 less than or equal to P less than or equal to 80 MPa), among a fluid lamellar (L-alpha) phase, a ripple gel (P-beta') phase and an interdigitated gel (L-betaI) phase, we have found a new phase with a single peak at around Q = 0.06 Angstrom(-1). This phase was characterized to be a swollen gel phase from the data analysis. The kinetics of the phase transition to the L-betaI phase was investigated, and the relaxation was much slower than the transition to the other bilayer structures. |
