These naturally occurring anti-vitamins interfere with specific vitamin functions, either by competing for binding sites or destroying the vitamin.
Anti-Vitamins and Their Sources — Matching
| Anti-Vitamin | Source | Vitamin Antagonised |
|---|---|---|
| 1. Anti-Vitamin A | (b) Raw soybean | Contains anti-vitamin A factors; destroyed by autoclaving |
| 2. Anti-Vitamin K | (c) Dicoumarol | Sweet clover poisoning, Warfarin; causes haemorrhage |
| 3. Anti-Vitamin B1 (Thiaminase) | (e) Raw fish / Bracken fern | Destroys thiamine → polyneuritis |
| 4. Anti-Biotin | (a) Avidin | Egg white injury factor (raw egg white); biotin is counter-factor |
| 5. Anti-Vitamin E | (d) Raw kidney bean | Contains anti-vitamin E factor |
Additional Anti-Nutritional Notes
- Avidin: Egg white injury factor; Biotin is the anti-egg white injury factor
- Oral contraceptives & TB drugs: antagonistic to Vitamin B6
- Dicoumarol: Also found in warfarin and sulfa drugs
Why Other Options Are Wrong
- 1-d, 2-c, 3-b, 4-a, 5-e → assigns raw kidney bean to anti-vitamin A (incorrect; soybean is the source)
- 1-c, 2-b, 3-a, 4-d, 5-e → multiple wrong pairings including Dicoumarol as anti-vitamin A
