DOIAbstract
The results of a study of the temperature and pressure dependence of isothermal compressibility of dimyristoylphosphatidylcholine (DMPC) are presented. The data were obtained using a small-angle X-ray scattering instrument in the Institute of Synthetic Polymer Materials (Moscow, Russia) and a device designed in the Laboratory of Neutron Physics, Joint Institute for Nuclear Research (Dubna, Russia), for studying the liquid systems by a volumetric P-V-T method. The minute baric investigation of the region of the main phase transition (transition from the gel phase into the liquid crystalline phase) was carried out. The points of the main phase transition were determined, and the phase diagram of DMPC was plotted over the pressure range of 1-8...
