Question

What is cellulose? Write short notes on it?

Answer 1

Cellulose:

• The chemical formula for cellulose is ${\left({\mathrm{C}}_6{\mathrm{H}}_{10}{\mathrm{O}}_5\right)}_{\mathrm{n}}$, where $\mathrm{n}$ can range from $500-5000$.
• In a linear chain, D-glucose units are joined at ${\mathrm{C}}_1-{\mathrm{C}}_4$.
• The chains can expand due to the beta-glycoside bonds, while intramolecular hydrogen bonds keep the chains stable.

Structure of Cellulose:

• Cellulose, is composed of unbranched chains of D – glucose monomers linked by $\mathrm{\beta }(1\to 4)$ glycosidic bonds.
• The structure of cellulose is shown below in the image.

Properties of Cellulose:

• It is tasteless and has no odor.
• It is water-soluble and biodegradable.

Uses of cellulose:

• It is used in manufacturing paper, cellulose fibers, rayon, etc.
• It is used in making explosives.
• It is used in manufacturing solvents, detergents, and adhesives.
