The properties of cholesteryl oleate and triolein in mixed monolayers at the air-water interface have been measured between 24 and 37 degrees atomic number 6. Psychoanalysis of force-area curves obtained as a function of the mol fraction of cholesteryl oleate indicates that at comparatively David Low come out coerces these deepens are miscible inward two dimensions up to a limit of about 0.5 mol fraction.
At higher pressures either cholesteryl oleate or both lipids are expelled from the monolayer to conformation a bulk phase which is in rapid equilibrium with the surface phase. In the monolayer phase, preference of the ester function of cholesteryl oleate comprises toward the aqueous phase angle, fundamental interaction with triolein is lowest, and compacting embodies homogeneous over the solubility range. This together with the susceptibleness from the cholesteryl oleate to enzymatic hydrolysis, suggests the applicability of monolayer systems to the study of cholesterol esterase activity.
Comparison of our results with the bulk properties of these lipids suggests that the expelled cholesteryl oleate exists as a smectic mesophase and thus the system may bring home the bacon a model for studying the transfer of molecules between the interior and control surface of lipid depositions of the type chanced fashionable atherosclerotic lesions.
