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).
Lactose is broken down by a protein called lactase, which acts as a pair of molecular scissors, snipping the lactose molecule in two. Anyone who drank milk as a baby carries a working version of the gene that codes for lactase. In lactose tolerant individuals, that gene keeps working into adulthood, producing the protein that digests lactose and makes eating ice cream a pleasant experience.
