Anti-Vitamins Matched with Their Sources
Match the anti-vitamins with their sources:
| Column A | Column B |
|---|---|
| 1. Anti-Vitamin A | (a) Avidin |
| 2. Anti-Vitamin K | (b) Raw soybean |
| 3. Anti-Vitamin B1 | (c) Dicoumarol |
| 4. Anti-Biotin | (d) Raw kidney bean |
| 5. Anti-Vitamin E | (e) Raw fish |
- 1-b, 2-c, 3-e, 4-a, 5-d — Correct Answer
- 1-b, 2-c, 3-a, 4-e, 5-d
- 1-d, 2-c, 3-e, 4-a, 5-b
- 1-a, 2-b, 3-c, 4-d, 5-e
Explanation:
Correct Answer: 1-b, 2-c, 3-e, 4-a, 5-d
Anti-nutritional factors that antagonise specific vitamins:
- Anti-Vitamin A → Raw soybean (b): Contains anti-vitamin A factors (lipoxidase enzyme destroys carotene/β-carotene) and also trypsin inhibitor, anti-vitamin D.
- Anti-Vitamin K → Dicoumarol (c): Found in sweet clover (Melilotus alba). Dicoumarol inhibits Vitamin K-dependent clotting factors (II, VII, IX, X). Warfarin (rat poison) has the same mechanism.
- Anti-Vitamin B1 (Thiaminase) → Raw fish (e): Thiaminase enzyme in raw fish and bracken fern destroys thiamine. Causes 'Chastek paralysis' in foxes and mink fed raw fish.
- Anti-Biotin → Avidin (a): Found in raw egg white. Avidin binds biotin irreversibly, preventing absorption — causes 'Egg white injury'. Cooking denatures avidin.
- Anti-Vitamin E → Raw kidney bean (d): Raw kidney beans contain anti-vitamin E factors.
