Ceramide trihexoside-The ceramide trihexosides are one of the families of glycolipids that contain the sugars bonded together in the order galactose-galactose-glucose- bonded to a ceramide. This ceramide is glycolipid is important in the genetic condition Fabry's disease, in which there is a genetic deficiency or decreased efficiency of the enzyme alpha-galactosidase A. Without this enzyme, ceramide trihexosides cannot be metabolized and hence, accumulate in the affected individual. As you can see, the enzyme galactosidase A has the word "galactose" in it, indicating that this enzyme metabolizes galactose from the glycolipid. Most enzymes are quite self-explanatory in telling what they do. You only need to know the root word. Fabry's disease is characterised by a visible red-purple skin appearance, liver failure, painful limbs, and other signs and symptoms.
