Thermodynamic Analysis of the Cation Binding to a Phosphatidylcholine Monolayer at a Polarised Interface between Two Immiscible Electrolyte Solutions.

Original language description

Thermodynamic analysis of the polarised interface between two immiscible electrolyte solutions (ITIES) was outlined, which accounts for the adsorption of phosphatidylcholine (PC) both as a zwitterion and a cation formed by the aqueous cation associationwith the zwitterionic PC form, as well as for the aqueous cation transfer facilitated by PC leading to its depletion from the interface. Electrocapillary equation was derived clarifying the physical significance of the surface charge density; the differential capacity and the PC surface excess concentration. The potential dependence of the interfacial tension calculated using the Damaskins adsorption model of a compound adsorbed in two different forms was found to agree well with that measured for the polarised water |1,2-dichloroethane interface in the presence of DL-alpha-dipalmitoylphosphatidylcholine. Experimentally observed effect of the nature of the aqueous cation on the interfacial tension was ascribed to the difference.
