The influence of pH on surface properties of lung surfactants

  title={The influence of pH on surface properties of lung surfactants},
  author={J. D. Amirkhanian and Thurman A Merritt},
Protein-lipid interactions at air-liquid interfaces are dependent on electrostatic charges, cations, anions, distribution of protons, and surface potential, which are influenced by pH changes. All of these factors may affect lung surfactant function. To verify the pH dependence of surface activity of pulmonary surfactant, we studied the in vitro effects of pH and Ca2+ on the surface tension-lowering abilities of various surfactants in an oscillating bubble surfactometer. Surface tension… CONTINUE READING
