Question

Lactose intolerance is due to the absence of which intestinal enzyme in humans?

Answer 1

Hi,hope this helps you...

Normally, lactose is broken up by an enzyme (protein that expedites chemical reactions in the body) called lactase. This enzyme is located on the lining of the intestines (the brush border) and helps to break up lactose into its smaller carbohydrate components, glucose and galactose. These two smaller molecules are more easily absorbed by the body and used for metabolism.
