Abstract

The ester reaction product of vitamin F with cholesterol, i.e cholesterol linoleate and/or cholesterol linolenate. These compounds are obtained by esterifying cholesterol of 70-75 per cent purity with linoleic acid which contains approximately 70 per cent linoleic acid plus linolenic acid.
