C. Dynamics of Membrane Lipids

Skills to Develop

  • state the different kinds of dynamical motions of double chain amphiphiles in lipid bilayers, differentiating between motion of entire molecules and motion within a molecule
  • describe experiments that could be used to study lateral and flip-flop diffusion in vitro and in vivo
  • explain the use of exogenous labels (fluorescent, radioactive, electron spin resonance) that allow laboratory determination of lipid location and movement
  • explain similarities and differences in measurement and explanations of phase transitions in water and in lipid vesicle
  • explain the biological effects and necessities of membrane dynamics
