Which from following pairs of carbohydrates contains galactose in both of them as one of the constituent ?
Which from following pairs of carbohydrates contains galactose in both of them as one of the constituent ?
Show Hint
Lactose is glucose plus galactose, and raffinose has galactose, glucose and fructose.
Updated On: Oct 1, 2026
- Sucrose and maltose
- Maltose and lactose
- Lactose and Raffinose
- Sucrose and lactose
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: List sugars containing galactose
Lactose (milk sugar) and raffinose are the two in the options that contain galactose.
Step 2: Look at the pairs
(A) has none, (B) has one of them, (D) has one of them, (C) has both.
Step 3: Conclusion
Option (C) is the pair where both sugars contain galactose.
Step 4: Reminder
Glucose and fructose alone make up sucrose, and two glucose units make maltose.
Final Answer:
Option (C) has galactose in both sugars. This is option (C). \[ \boxed{\text{(C) }\text{Lactose and Raffinose}} \]

- 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
