Cellulose

Definition

Cellulose is a complex carbohydrate composed of glucose units that forms the main constituent of the cell wall in most plants.

Purpose

Cellulose serves as a critical structural component in plant cell walls, providing rigidity and strength. It is also utilized in various industrial applications, including paper production, textiles, and as a biodegradable material in manufacturing.

Examples of Use

1. Paper Production: Cellulose is the primary ingredient in paper and cardboard manufacturing.
2. Textiles: Used in producing natural fibers like cotton and rayon.
3. Bioplastics: Cellulose-based bioplastics are used as an eco-friendly alternative to conventional plastics.

Related Terms

• Lignin: A complex organic polymer that binds with cellulose fibers, providing additional strength to plant cell walls.
• Hemicellulose: A group of complex carbohydrates that, along with cellulose, form the plant cell wall.
• Glucose: The simple sugar units that make up cellulose.

Notes

• Cellulose is the most abundant organic polymer on Earth.
• It is indigestible by humans but is a critical component in the diet of herbivores.
