Lactase (a member of the beta-galactosidase group of enzymes) splits milk sugar (lactose) into the two simple sugars glucose and galactose. Found exclusively in mammalian milk, lactose is only one sixth as sweet as cane or beet sugar (sucrose).
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.
