Glycosidases catalyze the hydrolysis of glycosidic bonds, the linkages that connect sugar units in molecules. Because these enzymes break glycosidic bonds, they can dismantle complex carbohydrates (polysaccharides) into simple sugars. They can also remove the carbohydrate portions attached to proteins (glycoproteins) and to lipids (glycolipids) by cleaving the glycosidic bonds that attach sugars to those molecules. So they can degrade the carbohydrate portions of all three types: complex carbohydrates, glycoproteins, and glycolipids.
