Area per Lipid in DPPC-Cholesterol Bilayers : Analytical Approach

  title={Area per Lipid in DPPC-Cholesterol Bilayers : Analytical Approach},
  author={Boris B. Kheyfets and Sergei I. Mukhin},
Area per molecule in a DPPC-Cholesterol bilayers depends non-linearly on the cholesterol concentration. Using flexible strings model of lipid membranes we calculate area per molecule in DPPC-Cholesterol mixtures in the biologically relevant concentrations range. Few parameters of the model are optimized for a perfect agreement with the area per lipid data available from molecular dynamics simulations. Lateral pressure at the hydrophilic interface, γ, is taken to be proportional to the… CONTINUE READING
