| Abstract: | We have carried out a detailed pressure study of the three phase transitions observed in hydrated dimyristoyl phosphatidylcholine (DMPC) containing 95% by weight of water. The P-T diagram shows a Gel III-Gel II-Gel I triple point at 3.5 kbar, 41[ddot]C. It is found that the Gel III phase can be obtained by pressure-annealing the sample for about 12 hours at room temperature. |
