Question

Maltose is formed of

• A. $\alpha$-glucopyranose and $\beta$-fructopyranose
• B. $\alpha$-glucopyranose and $\alpha$-glucopyranose
  
• C. $\beta$-galactopyranose and $\beta$-galactopyranose
• D. $\alpha$-galactopyranose and $\alpha$-galactopyranose

Answer 1

Answer: (B)

$\alpha$-glucopyranose and $\alpha$-glucopyranose

Maltose is the a disaccharide which is formed by the linkage of alpha 1,4 glucose molecules. Amylase is a enzyme which helps in the digestion of the starch. It acts on the glycosidic bonds of the maltose and converts into simpler compounds. It helps in the hydrolysis of this bond. It can change maltose to monomer unit of the glucose.

So, the correct answer is option B.
