Which of the following is an example of polysaccharide*CelluloseFructoseGalactoseLactose

Identifying Polysaccharides

1. Understanding Polysaccharides: A polysaccharide is a type of carbohydrate that consists of long chains of monosaccharide units. They serve various functions in living organisms, primarily as energy storage and structural components.

2. Analyzing the Options:

   • Cellulose: This is a polysaccharide composed of β-glucose monomers and is a major component of plant cell walls. It is an example of a structural polysaccharide.
   • Fructose: This is a monosaccharide, specifically a simple sugar found in many plants.
   • Galactose: Similar to fructose, this is also a monosaccharide and not a polysaccharide.
   • Lactose: This is a disaccharide composed of two monosaccharides (glucose and galactose) and is not a polysaccharide.

3. Conclusion: Among the options provided, Cellulose is the only polysaccharide.

Final Answer

Cellulose is an example of a polysaccharide.
