Description and Uses

D-Galactose is a monosaccharide sugar that serves as an energy source and glycosylation component. It is a C-4 epimer of glucose and often used as a source of carbon in culture media. Galactose is a component of the disaccharide lactose and released upon hydrolysis by β-galactosidase enzymes. It is converted to glucose via the Leloir pathway or metabolized via an alternative pathway, such as the DeLey-Doudoroff pathway.

Galactose is a simple monosaccharide used as a component of the galactosyltransferase labeling buffer. It serves as an energy source and an important constituent of glycolipids and glycoproteins. Since it is a component of antigens, it plays a vital role in the determination of blood type within the ABO blood group system.
