"Lactose is a disaccharide that is the principal carbohydrate found in milk and other dairy products. To digest lactose the enzyme lactase is required to catalyse the hydrolysis reaction to produce the monosaccharides glucose and galactose. This enzyme is usually present at birth but often decreases in activity as the child matures. The condition where an individual has a deficiency of lactase is known as lactose intolerance and produces symptoms such as nausea, cramps, bloating, gas, and diarrhea.
