Brush-border lactase-phlorizin hydrolase (beta-galactosidase)
Cofactors used
What it does, reaction by reaction
Galactose Metabolism Carbohydrate Metabolism · Cytosol
Lactose + H2O → glucose + galactose
Converts Lactose H2O into Glucose Galactose
› Notes
Brush-border lactase-phlorizin hydrolase (beta-galactosidase) hydrolyzes dietary lactose in the small-intestinal lumen/brush border. This digestive precursor reaction requires water; lactase deficiency impairs galactose generation from lactose but is distinct from inherited Leloir-pathway disorders.
