Match the column: Carbohydrate classification
| Table-A (Type) | Table-B (Example) |
|---|---|
| 1. Raffinose | (a) Monosaccharide |
| 2. Cellobiose | (b) Homopolysaccharide |
| 3. Fructose | (c) Disaccharide |
| 4. Cellulose | (d) Heteropolysaccharide |
| 5. Hemicellulose | (e) Trisaccharide |
- 1-e, 2-c, 3-a, 4-b, 5-d — Correct Answer
- 1-c, 2-e, 3-a, 4-d, 5-b
- 1-e, 2-a, 3-c, 4-b, 5-d
- 1-d, 2-c, 3-a, 4-b, 5-e
Explanation:
Correct Answer: 1-e, 2-c, 3-a, 4-b, 5-d
Classification of carbohydrates by number of monosaccharide units: Raffinose = Trisaccharide; Cellobiose = Disaccharide; Fructose = Monosaccharide; Cellulose = Homopolysaccharide; Hemicellulose = Heteropolysaccharide.
Carbohydrate Classification — Complete Reference
| Carbohydrate | Class | Components/Notes |
|---|---|---|
| Fructose | Monosaccharide | Hexose sugar (6C) |
| Cellobiose | Disaccharide | Glucose + Glucose (β-1,4 linkage) |
| Raffinose | Trisaccharide | Glucose + Galactose + Fructose |
| Cellulose | Homopolysaccharide | Only glucose units; β-1,4 bonds |
| Hemicellulose | Heteropolysaccharide | Multiple different monosaccharides |
Key Linkage Differences
- Maltose: Glucose-Glucose with α-1,4 glycosidic bond (digestible).
- Cellobiose: Glucose-Glucose with β-1,4 glycosidic bond (not digestible by mammals without β-glucosidase).
- Raffinose = anti-nutritional trisaccharide in legumes — causes flatulence in pigs.
Why Other Options Are Wrong
- All other options misplace at least one carbohydrate — particularly confusing Raffinose (trisaccharide) with disaccharides, or Hemicellulose with homopolysaccharides.
