the analogous investigation of the hydrolysis of beta-d-fucoside , beta-d-galactoside and alpha-l-arabinoside with a similar structure at c1 -- c4 of the pyranose ring demonstrated that these glycosides were split by the same enzyne , beta-d-fucoside ( beta-d-galactoside , alpha-l-arabinoside ) hydrolase , the activity of which is decreased dramatically in gm1-gangliosidosis .
