The study of Cholesterol Ester in Lanolin

Abstract

It is known that there is a regularity in acyl group at each glyceride position of natural fats and oils.
Lanolin, which is chemically a complex of esters 75 alcohols and 138 fatty acids, were separated by TLC and its 5 fractions were obtained. During the coures of analysis, fatty acids were identified by GLC. We speculated that there was also a regularity in acyl group at each alcohol position. Normal fatty acids other than hydroxy fatty acids as a group exhibited obvious preference for cholesterol and iso-fatty acids were distributed at lanosterol position and hydroxy fatty acids were distributed at fatty alcohol position.
