Beschreibung

Anwendung

Versatile ligand for asymmetric catalysis. Ligand used for preparing Jacobsen′s catalyst suitable for enantioselective epoxidation of olefins lacking functional groups.

Amylases from Aspergillus oryzae are used to prevent staling in the baking industry, clarify haze from fruit juices and alcoholic beverages, and produce glucose and maltose syrup products.

Biochem./physiol. Wirkung

α-amylase catalyzes the hydrolysis of internal α-1,4-O-glycosidic bonds in starches to release α-anomeric sugars.

Lipases catalyze the hydrolysis of triacylglycerols into glycerol and free fatty acids.
