Is alpha glucosidase same as amyloglucosidase?

No, alpha-glucosidase and amyloglucosidase are not the same enzyme, although they both play roles in carbohydrate metabolism. Alpha-glucosidase primarily catalyzes the hydrolysis of terminal non-reducing alpha-D-glucose residues in oligosaccharides and polysaccharides, while amyloglucosidase (also known as glucoamylase) breaks down starch and glycogen by cleaving off glucose units from the ends of the chains. Their specific functions and substrate specificity differ, even though both contribute to the digestion of carbohydrates.
