The effect of the phase transition on the hydration and electrical conductivity of phospholipids

摘要: Abstract Adsorption isotherms for various saturated phosphatidylcholines have been obtained. Lipids above and below their phase transition temperature differ only in the amount of water adsorbed not nature adsorption isotherms. Cholesterol has an effect similar to that increasing unsaturation hydrocarbon chains. Decreasing length chains lipids no on If chain is short enough so are temperature, however, a large increase occuŕs. All phospholipids exhibit rapid electrical conductivity few molecules per lipid molecule. show saturation at greater amounts water; shape region depends whether or temperature. The activation energy process hydrated “liquid-like” crystalline state, being lower liquid-like state. temperatures, energies than if they lowers energy. can be characterized by different energies, depending both upon physical state presence
