Ion Transport through Monolayers and Interfacial Films
Ion transport through monolayers and through several molecules of thick films at the mercury/water interface is discussed. The permeability of the monolayer is described by a rate constant, k(c). The permeability of a thin but not monomolecular film is expressed as a function of the thickness of the film, the diffusion coefficient of the permeant in the film, and the distribution coefficient be...
متن کاملIsotherms of Dipalmitoylphosphatidylcholine (DPPC) Monolayers: Features Revealed and Features Obscured
Valuable as they are, isotherms may display features that Pressure–area isotherms of dipalmitoylphosphatidylcholine are difficult to interpret, or may even be featureless under (DPPC) exhibit a two-phase region wherein domains of a liquidconditions where interesting things are happening. For examcondensed (LC) phase are dispersed in the less ordered liquidple, the nonhorizontal nature of the pl...
متن کاملPhase behavior of lipid monolayers containing DPPC and cholesterol analogs.
We investigate the miscibility phase behavior of lipid monolayers containing a wide variety of sterols. Six of the sterols satisfy a definition from an earlier study of "membrane-active sterols" in bilayers (cholesterol, epicholesterol, lathosterol, dihydrocholesterol, ergosterol, and desmosterol), and six do not (25-hydroxycholesterol, lanosterol, androstenolone, coprostanol, cholestane, and c...
متن کاملMolecular dynamics simulation of hydrated DPPC monolayers using charge equilibration force fields
We present results of molecular dynamics simulations of a model DPPC-water monolayer using charge equilibration (CHEQ) force fields, which explicitly account for electronic polarization in a classical treatment of intermolecular interactions. The surface pressure, determined as the difference between the monolayer and pure water surface tensions at 323 K, is predicted to be 22.92 ±1.29 dyne/cm,...
متن کاملEffect of Perfluoroalkyl Endgroups on the Interactions of Tri-Block Copolymers with Monofluorinated F-DPPC Monolayers
We studied the interaction of amphiphilic and triphilic polymers with monolayers prepared from F-DPPC (1-palmitoyl-2-(16-fluoropalmitoyl)-sn-glycero-3-phosphocholine), a phospholipid with a single fluorine atom at the terminus of the sn-2 chain, an analogue of dipalmitoyl-phosphatidylcholine (DPPC). The amphiphilic block copolymers contained a hydrophobic poly(propylene oxide) block flanked by ...
