摘要
A new type of lipid organization is observed in mixtures of phosphatidylcholine with cardiolipin (in the presence of Ca2+), monoglucosyldiglyceride and phosphatidylethanolamine (in the presence of cholesterol). This phase is characterised by an isotropic 31P NMR signal and is visualised by freeze-fracturing as particles and pits on the fracture faces of the lipid bilayer. As the most favourable model for this phase we propose the inverted micelle sandwiched in between the two monolayers of the lipid bilayer. © 1979.
