Chitin

Chitin is a natural polysaccharide, a complex carbohydrate that provides structural support in various organisms. It is similar to cellulose but has nitrogen-containing groups, making it stronger and more flexible. Chitin forms the exoskeletons of insects, spiders, and crustaceans like crabs and shrimp, offering protection and support. It’s also found in the cell walls of fungi and some algae. Chemically, chitin is durable and biodegradable, making it valuable in medicine, agriculture, and biodegradable materials. Overall, chitin is an important biological material that contributes to the structural integrity of many natural organisms.
