In the context of carbohydrate digestion, which enzyme is responsible for the hydrolysis of $\alpha$-1,6-glycosidic bonds in branched polysaccharides?

Solution

1. Pancreatic amylase hydrolyzes $\alpha$-1,4-glycosidic bonds but cannot break $\alpha$-1,6-glycosidic bonds.
2. This results in the formation of $\alpha$-limit dextrins.
3. The enzyme $\text{isomaltase}$ (or $\alpha$-dextrinase) is required to hydrolyze the $\alpha$-1,6-glycosidic bonds.
4. Hence the answer is (C).
