Question

Enzyme involved in hydrolysis of starch to maltose is

• A. Protease
• B. Amylase
• C. Lactase
• D. Maltase

Answer 1

The correct option is B Amylase

Starch is used as food reserves in plants. It is a polymer of glucose. It is formed by the attachment of glucose unit by glycosidic bonds. The basic formula of starch is (C${}_6$H${}_{10}$O${}_5$)n.

Maltose is the disaccharide which is formed by the linkage of alpha 1,4 glucose molecules.

Amylase is an enzyme which helps in the digestion of the starch. It acts on the glycosidic bonds of the starch and converts into simpler compounds. It helps in the hydrolysis of this bond. It is present in the saliva and the pancreas secretion in humans and helps in intracellular digestion of starch. It can change starch into maltose by breaking glycosidic bonds.

So, the correct answer is option B.
