Match: Common Names of Sugars
Match the column:
| Table-A (Common Name) | Table-B (Scientific Name) |
|---|---|
| 1. Brain sugar | (a) Lactose |
| 2. Blood sugar | (b) Fructose |
| 3. Milk Sugar | (c) Glucose |
| 4. Cane Sugar | (d) Galactose |
| 5. Fruit Sugar | (e) Sucrose |
- 1-a, 2-c, 3-d, 4-e, 5-b
- 1-d, 2-c, 3-a, 4-e, 5-b — Correct Answer
- 1-d, 2-b, 3-a, 4-e, 5-c
- 1-c, 2-d, 3-a, 4-e, 5-b
Explanation:
Correct Answer: 1-d, 2-c, 3-a, 4-e, 5-b
Common names of sugars refer to their biological origin or characteristic location in the body. Each has a precise scientific (chemical) name.
Common vs Scientific Names of Sugars
| Common Name | Scientific Name | Notes |
|---|---|---|
| 1. Brain sugar | (d) Galactose | Key component of cerebrosides in brain tissue; hexose sugar |
| 2. Blood sugar | (c) Glucose | Primary energy source in blood; normal blood glucose 70–110 mg/dl |
| 3. Milk sugar | (a) Lactose | Disaccharide: Glucose + Galactose; found in milk |
| 4. Cane sugar | (e) Sucrose | Disaccharide: Glucose + Fructose; from sugarcane |
| 5. Fruit sugar | (b) Fructose | Naturally occurring in fruits and honey; sweetest sugar |
Disaccharide Composition
- Sucrose = Glucose + Fructose
- Lactose = Glucose + Galactose
- Maltose = Glucose + Glucose (α-1,4 glycosidic linkage)
- Cellobiose = Glucose + Glucose (β-1,4 glycosidic linkage)
Why Other Options Are Wrong
- 1-a, 2-c, 3-d, 4-e, 5-b → assigns Lactose to brain sugar (incorrect; that is Galactose)
- 1-d, 2-b, 3-a, 4-e, 5-c → assigns Fructose to blood sugar (incorrect; Glucose is blood sugar)
