Raffinose on hydrolysis gives

Options

A. Glucose , fructose and lactose
B. Glucose , fructose and galactose
C. Fructose , glucose and erithrose
D. Glucose , fructose and mannose

Answer

To solve the question "Raffinose on hydrolysis gives," we need to understand what raffinose is and what happens during its hydrolysis.

### Step-by-Step Solution:

1. **Identify Raffinose**: Raffinose is a type of carbohydrate known as a trisaccharide. This means it is composed of three monosaccharide units.

2. **Determine the Monosaccharides in Raffinose**: The three monosaccharides that make up raffinose are:
- Glucose
- Fructose
- Galactose

3. **Understand Hydrolysis**: Hydrolysis is a chemical process that involves the breaking down of a compound by reaction with water. In the case of raffinose, hydrolysis will break it down into its constituent monosaccharides.

4. **Perform Hydrolysis on Raffinose**: When raffinose undergoes hydrolysis, it yields:
- 1 molecule of glucose
- 1 molecule of fructose
- 1 molecule of galactose

5. **Evaluate the Options**: Now, we need to compare our findings with the given options:
- Option A: Glucose, Fructose, Lactose (Incorrect, as lactose is a disaccharide)
- Option B: Glucose, Fructose, Galactose (Correct)
- Option C: Fructose, Glucose, Erythrose (Incorrect, erythrose is a four-carbon sugar)
- Option D: Glucose, Fructose, Mannose (Incorrect, mannose is not a component of raffinose)

6. **Conclusion**: The correct answer is that raffinose on hydrolysis gives glucose, fructose, and galactose.

### Final Answer:
Raffinose on hydrolysis gives glucose, fructose, and galactose.
