The autoxidative formation of 7-ketocholesterol and diols from aqueous cholesterol dispersions and from cholesterol monomolecular films has been studied as a function of time. The rate of oxidation of cholesterol is much faster at the surface than in the bulk. Whereas more than one-half of the cholesterol is oxidized at the surface within 8 hr at room(More)
The apparent condensation effect observed with mixed monolayers of lecithin and cholesterol has been examined with respect to both molecular interaction and molecular cavity models. For each, model equations are presented which predict the surface areas of the film components as a function of the mole fraction of each component. For mixed monolayers where(More)
