-

Sinapis alba

-

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

-

Sinapis alba

-

the acyltransferase in Sinapis alba roots exhibits group specificity for natural sterols, which are 3beta-hydroxysterols containing a planar ring system and differing only in number or position of double bonds or in the structure of side chain
