Question:
Glycosidic linkage between C\(_1\) of \(\alpha\)-glucose and C\(_2\) of \(\beta\)-fructose is found in:
Glycosidic linkage between C\(_1\) of \(\alpha\)-glucose and C\(_2\) of \(\beta\)-fructose is found in:
Show Hint
Sucrose is a non-reducing sugar as both anomeric carbons of glucose and fructose are involved in glycosidic linkage.
Updated On: Mar 25, 2025
- maltose
- sucrose
- lactose
- amylose
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Glycosidic Linkage
Glycosidic bonds are covalent bonds formed between sugar molecules through dehydration synthesis.
The type of glycosidic bond determines the digestibility and function of the disaccharide.
Step 2: Comparison of Linkages
Maltose consists of two glucose units linked by a C\(_1\)-C\(_4\) \(\alpha\)-glycosidic bond.
Sucrose has a glycosidic bond between C\(_1\) of \(\alpha\)-glucose and C\(_2\) of \(\beta\)-fructose.
Lactose is made up of galactose and glucose with a C\(_1\)-C\(_4\) glycosidic bond.
Amylose consists of glucose monomers linked by C\(_1\)-C\(_4\) \(\alpha\)-glycosidic bonds.
Final Answer: Since sucrose contains an \(\alpha\)-glucose and a \(\beta\)-fructose linked at C\(_1\)-C\(_2\), the correct answer is (B).
