Galactosylceramidase (or galactocerebrosidase) is an enzyme that in humans is encoded by the GALC gene.[1][2] Galactosylceramidase is an enzyme which removes galactose from ceramide derivatives (galactocerebrosides).
Galactosylceramidase is a lysosomal protein which hydrolyzes the galactose ester bonds of galactocerebroside, galactosylsphingosine, lactosylceramide, and monogalactosyldiglyceride.[1] Mutations in this gene have been associated with Krabbe disease, also known as globoid cell leukodystrophy.[1]
