Gravity influences membrane processes. Studies show higher gramicidin channel current in horizontal membranes compared to vertical ones, confirming gravity

Area of Science:

  • Biophysics
  • Physical Chemistry

Background:

  • Theoretical models suggest gravity impacts membrane-solution interfaces differently based on orientation.
  • The membrane-solution interface is crucial in many biological systems.

Purpose of the Study:

  • To experimentally investigate the effect of gravity on membrane processes.
  • To compare gramicidin channel activity in vertically versus horizontally oriented membranes.

Main Methods:

  • Incorporation of gramicidin into phosphatidylserine planar bilayer membranes.
  • Measurement of single channel events in 0.1 M KCl solution at pH 7 and room temperature.
  • Application of a transmembrane potential of +/- 70 mV.

Main Results:

  • Mean channel current was approximately 20% higher in horizontally oriented membranes.

  • Observed results align with theoretical predictions regarding gravity's influence.

    • Conclusions:

    • Gravity demonstrably affects membrane processes.
    • This effect is mediated through interactions with the membrane-solution interface.
