Abstract
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.
摘要
研究了pH值对由二棕榈酰磷脂酸（DPPA）和硫代二棕榈酰磷脂酸（thio-DPPA）形成的双分子层膜（BLM）中通过电导率跃变测量的相变的影响。展示了这两种脂质在pH依赖性上的差异。相应的计算揭示了分子间磷酸-磷酸氢键在BLM诱导电导率中的重要性。
