Kinetic Evidence for Interdigitation in Model Lipid Bilayers. (Reannouncementwith New Availability Information)

摘要

Pseudoglyceryl ammonium ion coliposomes constructed from an arachidoyl probelipid (6-F) and either stearoyl or palmitoyl host lipids (5-NF or 4-NF) display unusually slow transverse bilayer migration ('flip-flop') of the arachidoyl probe molecule compared with the behavior of shorter probe lipids in similar colipsomes. This phenomenon is probably associated with interdigitation of the arachidoyl lipid across the bilayer's midplane. Liposomes, Dynamics, Kinetics, Flip-flop.
