ON THE HYPERICIN INTERACTION WITH THE ARTIFICIAL LIPID MEMBRANE IN THE PRESENCE OF LYOTROPIC ANIONS

摘要

The modifications induced by hypericin on the electric properties of the artificial lipid bilayers suggest that it has apparent stabilizing effects on the membrane against strong chaotropic anions. We imply that this is due to the interference of hypericin's insertion into the bilayers with the mechanisms by which the lyotropic anions alter the electrical surroundings of the bilayer and/or the intrinsic membrane dipole potential.
