Abstract
The principal dietary sources of galactose are milk and certain milk products in which it occurs mainly as a component of lactose. Lactose is hydrolysed by β-galactosidase (lactase) in the brush border of the small intestine to its component monosaccharides, galactose and glucose, which are both absorbed by an active transport mechanism across the gut wall into the blood.
