Structure and conformation of bipolar tetracether lipid membranes derived from thermoacidophilic archaeon sulfolobus acidocaldarius as revealed by small-angle X-ray scattering and high-pressure FT-IR spectroscopy

Article Abstract:

A study was conducted on the phase behavior, conformation, and structure of bipolar tetracether liposomes composed of the polar lipid fraction E (PLFE) isolated from the thermoacidophilic archaeon sulfolobus acidocaldarius by small-angle X-ray scattering (SAXS) and high-pressure Fourier transform infrared spectroscopy (FT-IR) at pD 2.15. The results provide new information on the phase behavior, conformation, and structure of PLFE liposomes also at high pressure.

How anesthetics, neurotransmitters, and antibiotics influence the relaxation processes in lipid membranes

Article Abstract:

The studies which demonstrate the influence of a drug on the relaxation time scale of domain formation processes is presented. The findings suggest that relaxation times are proportional to the excess heat capacity.
