Earlier, the dipole moment of the phosphocholine group was cal- culated, which, in its 200 declination with the membrane surface, was found to induce a very high 90 mV dipole potential in the membrane environment [46, 47].
Fig. 5.11 Alamethicin channel activity in a 1,2-Dioleoyl-sn-Glycero-3-Phosphocholine (DC18 1 PC)/n-decane bilayer. a and b, long- (30 s) and short- (0.1 s) time records, respectively, of current traces through alamethicin channels. c current level histograms obtained from 30 s traces.
