Galactose is a type of sugar found in milk products and sugar beets.
Galactose is a monosaccharide constituent, together with glucose, of the disaccharide lactose. The hydrolysis of lactose to glucose and galactose is catalyzed by the enzyme beta-galactosidase, a lactase.
Galactose is a monosaccharide. It contains six carbons and an aldehyde group and is classified as an aldose and a hexose.
