  • Title: [Conductivity of bilayer lipid membranes of phosphatidic acid at phase transitions, induced by temperature and pH].
    Author: Antonov VF, Vasserman AN, Mol'nar AA, Kozhomkulov ET, Linke L.
    Journal: Biofizika; 1982; 27(5):822-6. PubMed ID: 7138932.
    Abstract:
    Conductivity of bilayer lipid membranes formed from synthetic phosphatic acid and its thioanalogs was studied. Conductivity of bilayer lipid membranes was shown to change spasmodically in the phase transition region. The temperature of conductivity jump decreased with pH shift from acid to alkaline region. The amplitude of conductivity jump attained 1.5-2 orders. The jump can be also obtained at constant temperature by changing the medium pH. The observed conductivity jumps are suggested to determine the phenomena of thermo- and chemoreception in biological membranes.
