- Chitin
Chitin is a structural polysaccharide. Insects and bees, like the one in the picture, and crustaceans use chitin to build their exoskeleton. Also, chitin can be found in the cell walls of fungi and in some other places. ...
- Cellulose
The cells of a plant are surrounded by a thick protective layer called the cell wall. Cellulose is a major component of this protective layer. Cellulose is a polysaccharide, a polymer of glucose, (carbohydrate) and it is the most abundant macromolecule...
