An enzyme that converts lactose into its more digestible simple sugar components: glucose and galactose. The lactase enzyme is available in liquid form to add to milk or in tablet form to take with solid food.
This is an enzyme that is used to break down the milk sugar and changes it into galactose and glucose. When person who suffers from lactase deficiency they experience diarrhea and abdominal cramping after consuming products containing milk and lactose.
Enzyme in certain yeasts and mammalian intestinal tracts that catalyzes converting lactose to glucose and galactose. Lactase tablets remove lactose from milk for people who are lactose intolerant. See next entry.
Lactase (LCT), a member of the Î²-galactosidase family of enzymes, is a glycoside hydrolase involved in the hydrolysis of the disaccharide lactose into constituent galactose and glucose monomers. In humans, lactase is present predominantly along the brush border membrane of the differentiated enterocytes lining the villi of the small intestine.
