Catalysis of the transfer of a galactose group from UDP-galactose to an acceptor molecule. Catalysis of the reaction: UDP-galactose + N-acetyl-D-glucosamine = UDP + N-acetyllactosamine. Catalysis of the transfer of a glycosyl group from a UDP-sugar to a small hydrophobic molecule. Catalysis of the transfer of a galactosyl group to an acceptor molecule, typically another carbohydrate or a lipid.
