WebLactulose is a ketose disaccharide, chemically known as 4-O -β- d -galactopyranosyl- d -fructose. The enzymes used for the biocatalytic production of lactulose are β-galactosidase (EC 3.2.1.23) and β-glycosidase (EC 3.2.1.21) – using lactose and fructose as a substrate. It can also be produced by the alkaline isomerization of lactose.
