Question

Identify correct conversion during acidic hydrolysis from the following: (A) Starch gives galactose.
(B) Cane sugar gives equal amount of glucose and fructose.
(C) Milk sugar gives glucose and galactose.
(D) Amylopectin gives glucose and fructose.
(E) Amylose gives only glucose.
Choose the correct answer from the options given below:

• A. (B), (C) and (E) only
• B. (B), (C) and (D) only
• C. (A), (B) and (C) only
• D. (C), (D) and (E) only

Hint:

Remember that sucrose gives glucose and fructose, lactose gives glucose and galactose, and starch yields glucose.

Answer 1

The Correct Option is A

• (B) Cane sugar (Sucrose) hydrolyzes into an equal mixture of glucose and fructose.
• (C) Milk sugar (Lactose) hydrolyzes into glucose and galactose.
• (E) Amylose hydrolyzes into only glucose since it is a straight-chain polysaccharide of glucose units.

• (A) is incorrect because starch does not give galactose; it breaks down into maltose and eventually glucose.
• (D) is incorrect because amylopectin hydrolyzes into glucose, not fructose.
