pH effect on phase transition measured by jump of conductance in the BLM formed from DPPA and thio-DPPA was studied. The difference of pH dependence for these two lipids was shown. The corresponding calculation discovered significance of intermolecular phosphate-phosphate hydrogen bonds in induced conductance of BLM.
