  • Title: Interconversion of bilayer phase transition temperatures between phosphatidylethanolamines and phosphatidylcholines.
    Author: Huang C, Wang ZQ, Lin HN, Brumbaugh EE, Li S.
    Journal: Biochim Biophys Acta; 1994 Jan 03; 1189(1):7-12. PubMed ID: 8305462.
    Abstract:
    High-resolution differential scanning calorimetric studies were performed to investigate the thermotropic phase behavior of 31 molecular species of phosphatidylethanolamines in excess water. Upon reheating, the aqueous dispersions of these lipids undergo the gel to liquid-crystalline phase transitions at well defined temperatures (Tm). These Tm values were shown to relate to the structural parameters of the underlying lipid molecules in a characteristic manner. Based on these observations, an interconversion of the Tm values between saturated phosphatidylethanolamines and phosphatidylcholines is established quantitatively for the first time.
