Galactosyl-oligosaccharides

Galactosyl-oligosaccharides (GOS) are non-digestible oligosaccharides which are qualified as functional foods. GOS are enzymatically synthesized from lactose by transgalactosylation catalyzed by the enzyme β-galactosidase. In this study, a method for immobilization of β-galactosidase from Kluyveromy

In the enzymatic hydrolysis of lactose, the enzyme b-galactosidase transfers a galactose moiety to an acceptor containing a hydroxyl group. If this acceptor is a water molecule, galactose is liberated (hydrolysis). When a sugar moiety acts as the acceptor, galactosyl-oligosac-charides (GOS) are form
