[The role of the state of protein-lipid interactions in stimulated membranes in the conformation of C40-carotenoids].
It was shown by Raman spectroscopy that conformation of carotenoid in the frog nerve membranes at rest and at propagation of rhythmic excitation depends on the state of protein-lipid interaction modified by exposition of the nerve in solution with trypsin, alpha-chymotrypsin, urea, glutaraldehyde, SH-reagents, isopropanol and system "Fe-ascorbate". It is suggested that the level of the protein-lipid interactions in excitable membranes with the intramembrane potential determines C40-carotenoid conformation at the propagation of rhythmic excitation by he nerve.
