A Study of Phase Transition of Lipids and Lipid Mixtures by Differential Scanning Calorimetry

摘要: The simple binary mixtures of pure phospholipids such as DPPC:DSPC and DPPC:DPPA were investigated with differential scanning calorimeter. thermotropic properties DPPC DSPC did not deviate much from the ideal curves that was obtained on varying either temperature or relative proportions phospholipids. This means two are completely miscible in liquid solid phase. But DPPA mixture deviated phase diagram. It resulted repulsion between head groups acidic Heat capacity suggested by Harden McConell calculated. larger was, sharper endothermic peak became.
