Identify the polysaccharide among the following :
Show Hint
Common disaccharides: Sucrose, Lactose, and Maltose.
Common monosaccharides: Glucose, Fructose, and Galactose.
- Fructose
- Maltose
- Glucose
- Cellulose
The Correct Option is D
Solution and Explanation
• Carbohydrates are classified based on the number of sugar units they produce upon hydrolysis.
• Monosaccharides: Single sugar units (cannot be hydrolyzed further).
• Disaccharides: Two sugar units.
• Polysaccharides: Hundreds to thousands of sugar units linked together.
Step 1: Categorizing the given options
1. Glucose: A monosaccharide (hexose).
2. Fructose: A monosaccharide (ketohexose).
3. Maltose: A disaccharide composed of two glucose units.
Step 2: Analyzing Cellulose
Cellulose is a high-molecular-weight polymer consisting of thousands of D-glucose units linked by \( \beta \)-1,4-glycosidic bonds.
It is the primary structural component of the cell walls of green plants.
Because it consists of many monosaccharide units, it is classified as a polysaccharide.
