What type of glycosidic bond is present in maltose?
What type of glycosidic bond is present in maltose?
Show Hint
Maltose is two alpha-D-glucose units joined by an alpha-1,4 linkage.
Updated On: Oct 1, 2026
- \(β\text{-}1,4\)
- \(α\text{-}1,4\)
- \(α\text{-}1,6\)
- \(β\text{-}2,4\)
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Know the sugar:
Maltose is obtained by hydrolysis of starch and gives two glucose molecules on further hydrolysis.
Step 2: The link:
Carbon 1 of the first glucose (alpha form) bonds through oxygen to carbon 4 of the second glucose, so the bond is alpha-1,4.
Step 3: Compare:
Cellobiose has beta-1,4, and amylopectin branches through alpha-1,6. So option (B) is for maltose.
Final Answer:
Option (B), alpha-1,4, is correct. \[ \boxed{\alpha\text{-1,4 (B)}} \]

- 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
