Catalysis of the transfer of a galactose group from UDP-galactose to an acceptor molecule. Catalysis of the reaction: UDP-galactose + N-acetyl-D-galactosaminyl-(N-acetylneuraminyl)-D-galactosyl-1,4-beta-D-glucosyl-N-acylsphingosine = UDP + D-galactosyl-1,3-beta-N-acetyl-D-galactosaminyl-(N-acetylneuraminyl)-D-galactosyl-D-glucosyl-N-acylsphingosine. 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.
