Neither α-amylase nor β-amylase can cleave the α(1→6)glycosidic bonds of amylopectin.Which of the following enzymes is required to completely hydrolyze starch?

Question

Quizplus · Accepted Answer

α-amylase and β-amylase can only cleave α(1→4) glycosidic bonds in starch, which generates maltose and other small oligosaccharides. However, the α(1→6) glycosidic bonds in amylopectin require the action of an additional enzyme, α(1→6)-glucosidase, to completely break down the starch into glucose. Glycogen phosphorylase and maltase are not involved in the breakdown of starch, and sucrase specifically cleaves sucrose, not starch. Therefore, A) α(1→6)-glucosidase is the best choice to completely hydrolyze starch.
