Lactase is a protein enzyme that digests (breaks down) lactose (milk sugar) into glucose and. galactose (smaller sugars). The chemical equation below illustrates what happens when the. enzyme lactase digests lactose (milk sugar).
The gene for lactase is known as LCT, and it is mostly expressed in cells in the epithelium of the small intestine. Although nearly everyone can produce the enzyme at birth, the majority of people outside Northern Europe lose the ability to produce a lot of it at some point during the first years of life.he gene for lactase is known as LCT, and it is mostly expressed in cells in the epithelium of the small intestine.
