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.
