Phospholipid phase transition temperature
WebIn Fig. 5.38A, the polymer with eleven methylene units possesses a monotropic liquid crystalline transition temperature at 97 °C, which is 48 °C above the glass transition temperature ( Tg = 49 °C). Both overall crystallization kinetics from the isotropic melt and the liquid crystal phase can be monitored, which is shown in this figure. WebThe lamellar phase was found to be oriented along the magnetic field. Further increase in temperature induced the formation of lipid vesicles. These transformations were explained using a transition model based on the migration of the peptide from the rim of the nanodiscs to the liquid-crystalline bilayer phase.
