Lactose Intolerance

Lactose intolerance is a gastrointestinal disease in which there occurs deficiency of an enzyme named lactase which hydrolyzes lactose to its components galactose and glucose. In the absence of this enzyme named lactase , lactose cannot be hydrolyzed and hence, it goes to colon where it is fermented by bacteria causing various gastrointestinal symptoms of lactase deficiency.
