Question

Match List-I with List-II

Choose the correct answer from the options given below:

• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
• (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
• (A) - (I), (B) - (IV), (C) - (II), (D) - (III)

Hint:

To solve this question quickly, identify myo-Inositol first as the cyclic sugar alcohol, which links (B) directly to (IV).
This leaves only options (C) and (D) as possibilities, and knowing that Ribitol is in riboflavin (flavin coenzymes) links (C) to (I).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Sugar alcohols (polyols) are sweetening agents and metabolic intermediates containing multiple hydroxyl groups. They are used in clinical applications and biochemical structures.

Step 2: Detailed Explanation:
Let us match each sugar alcohol with its corresponding property or clinical use:
(A) Sorbitol is a slowly absorbed carbohydrate alcohol that acts as an osmotic laxative (II) in the gastrointestinal tract by pulling water into the colon to ease constipation.
(B) myo-Inositol is a carbocyclic sugar alcohol (IV) that plays an essential structural role in eukaryotic cell membranes as part of phosphatidylinositol.
(C) Ribitol is a pentose-derived sugar alcohol that serves as a building block in the synthesis of riboflavin and other flavin coenzymes (I) such as FAD and FMN.
(D) Mannitol is an isomer of sorbitol that functions as an osmotic diuretic (III), widely used in emergency medicine to reduce intracranial pressure and treat acute kidney failure.
Combining these matches, we get: (A) - (II), (B) - (IV), (C) - (I), (D) - (III).

Step 3: Final Answer:
This matching sequence is found in option (C).
