In enzymology a lactosylceramide 4-alpha-galactosyltransferase (EC 2.4.1.228) is an enzyme that catalyzes the chemical reactionUDP-galactose + beta-D-galactosyl-(1->4)-D-glucosylceramide UDP + alpha-D-galactosyl-(1->4)-beta-D-galactosyl-(1->4)-D- glucosylceramideThus the two substrates of this enzyme are UDP-galactose and [[beta-D-galactosyl-(1->4)-D-glucosylceramide]] whereas its 3 products are UDP [[alpha-D-galactosyl-(1->4)-beta-D-galactosyl-(1->4)-D-]] and glucosylceramide.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
