Lactose synthase is an enzyme that generates lactose from glucose and UDP-galactose.It is classified under EC 2.4.1.22.It consists of N-acetyllactosamine synthase and alpha-lactalbumin. Alpha-lactalbumin which is expressed in response to prolactin increases the affinity of N-acetyllactosamine synthase for its substrate causing increased production of lactose during lactation.
