Funkcija[uredi | uredi izvor]

Galaktocerebrozidi su obilni sfingolipidi mijelinske membrane centralnog i perifernog nervnog sistema i također su prisutni u malim količinama u bubrezima. Ključni enzimski korak u biosintezi galaktocerebrozida sastoji se od prijenosa galaktoze u keramid kataliziranog UDP-galaktoza keramid galaktoziltransferaza (CGTransferaza 1.45). Enzim koji je kodiran CGT genom prvi je uključen u kompleksnu biosintezu lipida u mijelinizirajućim oligodendrocitima.^[6]
