Water permeability and mechanical strength of polyunsaturated lipid bilayers.
Micropipette aspiration was used to test mechanical strength and water permeability of giant-fluid bilayer vesicles composed of polyunsaturated phosphatidylcholine PC lipids. Eight synthetic-diacyl PCs were chosen with 18 carbon chains and degrees of unsaturation that ranged from one double bond (C18:0/1, C18:1/0) to six double bonds per PC molecule (diC18:3). Produced by increasing pipette pre...
متن کاملWater Permeability of Asymmetric Planar Lipid Bilayers
To understand how plasma membranes may limit water flux, we have modeled the apical membrane of MDCK type 1 cells. Previous experiments demonstrated that liposomes designed to mimic the inner and outer leaflet of this membrane exhibited 18-fold lower water permeation for outer leaflet lipids than inner leaflet lipids (Hill, W.G., and M.L. Zeidel. 2000. J. Biol. Chem. 275:30176-30185), confirmin...
متن کاملA comment on the water permeability through planar lipid bilayers
Dear Sir: In a recent article, Finkelstein (1976) has shown that the measured water permeabil i ty th rough a leci thin-decane planar bilayer m em b ran e is similar to the calculated permeabili ty t h rou g h a sheet o f n h e x a d e c a n e 50 ,~ thick. Th a t is, the measured water permeabil i ty, Pa, was found equal to DKhc/AX, where D is the diffusion constant o f water in water, Khe is t...
متن کاملTheory of Passive Permeability through Lipid Bilayers
Recently measured water permeability through bilayers of different lipids is most strongly correlated with the area per lipid A rather than with other structural quantities such as the thickness. This paper presents a simple three-layer theory that incorporates the area dependence in a physically realistic way and also includes the thickness as a secondary modulating parameter. The theory also ...
متن کاملThe effect of lipid oxidation on the water permeability of phospholipids bilayers.
The effect of lipid oxidation on water permeability of phosphatidylcholine membranes was investigated by means of both scattering stopped flow experiments and atomistic molecular dynamics simulations. Formation of water pores followed by a significant enhancement of water permeability was observed. The molecules of oxidized phospholipids facilitate pore formation and subsequently stabilize wate...
