enzyme has an absolute requirement for a beta-configuration of the hydroxyl group at C-3, rate of esterification is higher for sterols containing a planar ring system, triacylglycerols with unsaturated fatty acids are used more efficiently than fatty acids saturated with equal chain length, triacylglycerols with fatty acids C6-C22 can be used as acyl donors
