WebLecithin–cholesterol acyltransferase (LCAT, also called phosphatidylcholine–sterol O-acyltransferase) is an enzyme, in many animals including humans, that converts free cholesterol into cholesteryl ester (a more hydrophobic form of cholesterol), which is then sequestered into the core of a lipoprotein particle, eventually making the newly … WebTherefore, the possibility that 25-hydroxycholesterol stimulated cholesteryl ester formation by increasing the amount of cholesterol available for esterification, rather than by acting directly on ACAT activity, was considered. Labeling experiments using [14C]-cholesterol have provided evidence for this assumption.

Wax Ester - an overview ScienceDirect Topics

Cholesteryl ester, a dietary lipid, is an ester of cholesterol. The ester bond is formed between the carboxylate group of a fatty acid and the hydroxyl group of cholesterol. Cholesteryl esters have a lower solubility in water due to their increased hydrophobicity. Esters are formed by replacing at least one –OH (hydroxyl) group with an –O–alkyl (alkoxy) group. They are hydrolyzed by pan… WebEsterification can increase the volatility of fatty acids, reduce dimerization in the vapor phase, and reduce adhesion.
