How are cellulose and chitin similar?
Cellulose and chitin are two of the most abundant natural polymers on Earth. They both have a fibrous structure and are composed of repeating units of monosaccharides. However, there are also some key differences between the two polymers.
Cellulose is a polysaccharide composed of glucose units. It is found in the cell walls of plants and is the main component of paper and cotton. Chitin is a polysaccharide composed of N-acetylglucosamine units. It is found in the exoskeletons of insects, crustaceans, and other arthropods.
Similarities between cellulose and chitin:
- Both are polysaccharides
- Both have a fibrous structure
- Both are composed of repeating units of monosaccharides
- Both are insoluble in water
- Both are biodegradable
- Both are renewable resources
