生化/生理作用

alpha-Lactose is the primary sugar present in milk and the main energy source to a newborn mammalian through its mother′s milk. It is digested by the intestinal lactase (EC 3.2.1.108), an enzyme expressed in newborns. The enzyme′s activity declines following weaning which can lead to lactose intolerance in adult mammals.
