The micellar behaviour of the binary mixed systems dihexanoylphosphatidylcholine (diC6PC)/diheptanoylphosphatidylcholine (diC7PC), diC7PC/dioctanoylphosphatidylcholine (diC8PC) and diC6PC/ diC8PC has been studied. Critical micelle concentrations of the mixtures were quantitatively estimated from surface tension measurements versus solution composition ...

Journal of the American Oil Chemists' Society, 1981
AbstractBecause of the increased domestic production of sunflower seed oil, by‐products of oil processing such as meal and lecithin will be in greater supply. Lecithin content varies according to the type of sunflower seed produced. Removal of this material is greatly affected by seed condition and processing conditions.

Determination of the structure of lecithins
Lipids, 1966AbstractA method is described for the determination of the classes of lecithins in terms of unsaturated and saturated fatty acids based on a total fatty acid composition, the composition of the fatty acids in the β‐position, and the amount of disaturated class determined via mercuric acetate adduct formation.

Binding of DDT to Lecithin [PDF]
Science, 1971 An interaction between DDT and lecithin is indicated by the reciprocal effects of each compound on the proton magnetic resonance spectrum of the other. The phosphoryl choline moiety of the lecithin and the benzylic proton of the DDT seem to be involved.

Sucrose influence on lecithin and polypyrrole lecithin bilayer membranes
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1989Abstract Lecithin and polypyrrole+lecithin membranes were coated with sucrose from a water solution. Changes of the membrane properties were investigated. A significant increase in the mechanical membrane stability was observed. The optimum sucrose concentration was determined.

Final Report on the Safety Assessment of Lecithin and Hydrogenated Lecithin
International Journal of Toxicology, 2001Lecithin is a naturally occurring mixture of the diglycerides of stearic, palmitic, and oleic acids, linked to the choline ester of phosphoric acid, commonly called phosphatidylcholine. Hydrogenated Lecithin is the product of controlled hydrogenation of Lecithin.

Adsorption of Lecithin by Cholesterol
Journal of Pharmaceutical Sciences, 1980Egg lecithin was adsorbed significantly by cholesterol monohydrate crystals. Adsorption data obtained at initial concentrations of less than 1.1 mM lecithin fitted the Langmuir equation. The calculated adsorption capacity suggested formation of a lecithin bilayer or a mixed bilayer of lecithin and cholesterol. The amount of lecithin adsorbed was highly
