Unique Distribution and Effect of Ergosterol in Lipid Membranes

Scientific Achievement

Revealing differences in fundamental structural and dynamical effect of ergosterol on a major eukaryotic model membrane (POPC) from those of cholesterol.

Significance and Impact

Potential relevance for anti-fungi medication.

Research Details

  • Combined neutron membrane diffraction (NMD), small-angle neutron scattering (SANS), neutron spin echo (NSE)and quasielastic neutron scattering (QENS) study
  • Shallower embedding of ergosterol; no membrane thickening induced; moderately increased rigidity which is reversed at high concentration; different diffusion model
