Abstract:
The dependence of the interfacial tension of a lipid membrane formed from phosphatidylserine on the pH of the aqueous solution has been studied. The model described the H(+) and OH(-) ions adsorption in the bilayer lipid surface has been presented in this work. We take suitable equations to describe the dependence of interfacial tension of a lipid bilayer membrane on H(+) and OH(-) ion concentrations. A theoretical equation is derived to describe this dependence in the range of pH, i.e. from 2 to 12.
