Galactose-1-phosphate uridylyltransferase
UTP--glucose-1-phosphate uridylyltransferase
Sucrose + Water → D-Fructose + D-Galactose
α-Lactose → D-Galactose + Melibiose
Stachyose → D-Galactose + Raffinose
D-Galactose + Glycerol ↔ Galactosylglycerol
D-Galactose + myo-Inositol ↔ Galactinol
D-Galactose + D-Mannose ↔ Epimelibiose
D-Galactose + Sorbitol ↔ Melibiitol
Adenosine triphosphate + D-Galactose → Adenosine diphosphate + Galactose 1-phosphate
Adenosine triphosphate + α-D-Glucose → Adenosine diphosphate + Glucose 6-phosphate
Uridine diphosphategalactose → Galactinol
D-Galactose + α-D-Glucose → Water + α-Lactose
Phosphate + α-D-Glucose → Glucose 6-phosphate + Water
Glucose 1-phosphate → Glucose 6-phosphate
Pyrophosphate + Uridine diphosphate glucose → Glucose 1-phosphate + Uridine triphosphate
Uridine diphosphategalactose → Uridine diphosphate glucose
Glucose 1-phosphate + Uridine diphosphategalactose → Galactose 1-phosphate + Uridine diphosphate glucose
D-Glucose + Uridine diphosphategalactose → Uridine 5'-diphosphate + α-Lactose
D-Galactose + NAD → Galactitol + NADH
