In [[enzymology]], a '''lactosylceramide beta-1,3-galactosyltransferase''' ({{EC number|2.4.1.179}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:UDP-galactose + D-galactosyl-1,4-beta-D-glucosyl-R <math>\rightleftharpoons</math> UDP + D-galactosyl-1,3-beta-D-galactosyl-1,4-beta-D-glucosyl-R

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[UDP-galactose]] and [[D-galactosyl-1,4-beta-D-glucosyl-R]], whereas its two [[product (chemistry)|products]] are [[uridine diphosphate|UDP]] and [[D-galactosyl-1,3-beta-D-galactosyl-1,4-beta-D-glucosyl-R]].

This enzyme belongs to the family of [[glycosyltransferase]]s, specifically the hexosyltransferases.  The systematic name of this enzyme class is '''UDP-galactose:D-galactosyl-1,4-beta-D-glucosyl-R beta-1,3-galactosyltransferase'''. Other names in common use include '''uridine diphosphogalactose-lactosylceramide''', and '''beta1->3-galactosyltransferase'''.
