Electrosorption of L-α-dipalmitoylphosphatidylcholine at the mercury solution interface

Electrocapillary curves were measured for L-α-dipalmitoylphosphatidylcholine in 97% (υ/υ) methanol-water solutions containing 0·01 M NH 4NO 3. The electrosorption isotherms are similar to those of simpler aliphatic compounds. Saturated coverage of the electrode surface with this lipid in 97% (υ/υ) m...

Description
Summary:Electrocapillary curves were measured for L-α-dipalmitoylphosphatidylcholine in 97% (υ/υ) methanol-water solutions containing 0·01 M NH 4NO 3. The electrosorption isotherms are similar to those of simpler aliphatic compounds. Saturated coverage of the electrode surface with this lipid in 97% (υ/υ) methanol-water was not possible owing to the formation of micelles in the bulk solution. It is shown that it is possible from the electrocapillary curves to estimate the critical micelle concentration of lipids in non-aqueous electrolyte solutions.
