title: A convenient evaluation of the stereoselectivity of lipase-catalyzed hydrolysis of tri-O-acylglycerols on a chiral-phase liquid chromatography.
abstract: A general method was developed using chiral-phase chromatography in order to evaluate the stereoselectivities of lipases-catalyzed hydrolysis of tri-O-acylglycerols independent of acyl groups. 1,2-Di-O-acyl-sn-glycerols or its enantiomer 2,3-di-O-acyl-sn-glycerols in the enzymatic reaction mixtures were derivatized to the key compound, 1,2-di-O-benzoyl-3-O-tert-butyldimethylsilyl-sn-glycerol 2 (+) or its enantiomer 2' (-), respectively. The enantiomers were separated on a chiral-phase HPLC, and the method was highly sensitive to determine the stereoselectivities of lipases.
