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).
Remember, lactase is an enzyme, and we describe enzymes as catalysts: a substance that helps chemical reactions happen without being used up. Each bit of enzyme can break down multiple molecules of milk sugar, so as long as you stir the glass and wait long enough, even a tiny bit of the enzyme is enough to break down all the lactose in the milk!
