Lactase - The enzyme for break the lactose

Lactase (also known as lactase-phlorizin hydrolase or LPH), belongs to the β-galactosidase enzymes family. It is present primarily along the brush border membrane of differentiated enterocytes lining the villi of the small intestine.
Lactase is a glycoside hydrolase involved in the hydrolysis of D-lactose to form D-galactose and D-glucose, which can then be absorbed through the intestinal walls and pass into the bloodstream.
In food, lactase is added to milk, thus hydrolyzing the lactose naturally present in milk and leaving a slightly sweet taste but easily digestible by everyone.
Its other role is a phlorizin hydrolase activity which consists in hydrolyzing phlorizin into phloretin and glucose, my phlorizin being a compound present in the bark of certain fruit trees which is used in the treatment of diabetes and hyperglycemia.
