Sterol glycosides and acylglycosides

Sterol glycosides are widely distributed in plants and are frequently accompanied by their 6-0-acyl derivatives. As might be expected, preparations have been obtained which glucosylate sterols with UDP-glucose as sugar donor  

Acylation of steroid glucosides is carried out by particulate preparations which catalyse the reaction  

A soluble transacylase from carrot and radish roots used digalactosyldiglyceride as the most effective acyl donor [9,14].
