Which from following carbohydrates produces glucose, galactose and fructose on hydrolysis?
Show Hint
Trisaccharides like Raffinose ($C_{18}H_{32}O_{16}$) yield 3 units on hydrolysis.
Updated On: May 14, 2026
- Maltose
- Stachyose
- Raffinose
- Lactose
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
The question asks for a carbohydrate that is a trisaccharide composed of three specific monosaccharide units: glucose, galactose, and fructose.
Step 2: Detailed Explanation:
1. Maltose: A disaccharide that yields two glucose molecules on hydrolysis.
2. Stachyose: A tetrasaccharide that yields one glucose, one fructose, and two galactose molecules.
3. Raffinose: A trisaccharide found in many plants. Upon complete hydrolysis, it yields one molecule of D-glucose, one molecule of D-galactose, and one molecule of D-fructose.
4. Lactose: A disaccharide that yields one glucose and one galactose molecule.
Step 4: Final Answer:
Raffinose produces glucose, galactose, and fructose on hydrolysis.

- Carbohydrates are essential for life in both plants and animals. Carbohydrates are used as storage molecules as starch in plants and glycogen in animals. Chemically, they are polyhydroxy aldehydes or ketones. On the basis of their behavior on hydrolysis, carbohydrates are classified as monosaccharides, oligosaccharides, and polysaccharides.
All monosaccharides are reducing sugars, i.e., they are oxidized by Tollens' reagent and Fehling’s solution. A monosaccharide like glucose is an aldose, and its molecular formula was found to be C6H12O6. After reacting with different reagents like HI, H2N–OH, Bromine water, (CH3)2O, etc., its structure was found to contain one aldehyde group, one primary alcoholic group (–CH2OH), and four secondary alcoholic groups (>CHOH).
Despite having the aldehyde group, glucose does not give some of the reactions of aldehyde groups like Schiff’s test or NaHSO3 addition. This explains the existence of glucose in two cyclic hemiacetal forms, which differ only in the configuration of the hydroxyl group at C–1.- CBSE Class XII - 2024
