Question:
Two monosaccharides are held together by __________ bond.
Two monosaccharides are held together by __________ bond.
Show Hint
Two sugar units join by losing a molecule of water between them.
Updated On: Nov 13, 2026
- disulphide
- hydrogen
- phospodiester
- glycosidic
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Disaccharides such as sucrose, maltose and lactose are formed when two monosaccharides combine.
Step 2: Bond formation
A hydroxyl group of one sugar reacts with a hydroxyl group of the other sugar and a water molecule is removed. The linkage formed is a C-O-C link called a glycosidic bond.
Step 3: Compare the options
Disulphide bonds join cysteine residues in proteins and phosphodiester bonds join nucleotides, while hydrogen bonds are weak attractions. The glycosidic bond is the answer.
Final Answer:
Two monosaccharides are held together by a glycosidic bond. \[ \boxed{\text{(D) }\text{glycosidic}} \]
