The autoxidation of the cholesteryl moiety of cholesteryl linoleate stabilized in aqueous colloidal suspension with sodium dodecyl sulfate has been studied at 85C. The overall rate of this oxidation is more rapid than that for unesterified cholesterol and oxidation also occurs to a greater extent for the linoleate ester. These results are in contrast to those for more saturated fatty acyl esters of cholesterol which show diminished susceptibility to attack by oxygen in such a system. Autoxidation of cholesteryl linoleate by an intramolecular free‐radical mechanism is considered.
