TL;DR: In mixed-lipid monolayers, the composition of the interface may affect the lipid-protein interactions in a non-proportional manner with respect to the relative amount of the individual lipid components.

TL;DR: The effect of temperature on the behaviour of four different gangliosides, sulphatide, ceramide, Cer and three neutral glycosphingolipids was investigated in monolayers at the air-NaCl (145 mM) interface and shows isothermal liquid-expanded----liquid-condensed transitions.

TL;DR: The oligosaccharide chain of glycosphingolipids (GSLs) has a marked influence on their thermotropic behavior, intermolecular packing and surface electrical potential, and interactions occurring among GSLs and phospholipid domains induce changes of the molecular area and surface potential that depend on the type of GSLs.

TL;DR: The results obtained show that the percentage of the total area occupied by the protein at the interface is an important parameter leading to lateral phase separations; the amount and area contribution of the protein accepted in the film before the components become immiscible increase with the complexity of the polar head group of the glycosphingolipids.

TL;DR: Spectral properties of Merocyanine 540 were used in an attempt to investigate the interfacial micropolarity of liposomes constituted by egg phosphatidylcholine with phosphorus with results that reveal a more polar microenvironment for interfaces containing anionic glycosphingolipids or PA compared to interfaces constituted by PC alone or PC with neutral glycosphers.
