Which polysaccharide is found in the exoskeleton of some animals? cellulose, starch, chitin

Chitin is a fascinating polysaccharide that provides strength and protection to the exoskeletons of arthropods like crabs, lobsters, and insects. It is similar in structure to cellulose, the primary component of plant cell walls, but has different functional properties. This tough and flexible substance is also found in the cell walls of fungi, demonstrating its versatility in nature! In the real world, chitin has garnered attention not just for its biological functions but also for its potent applications. It’s being explored for biomedical uses such as wound dressings, drug delivery systems, and even in water purification. With sustainability becoming ever more critical, chitin recycling, such as deriving it from crustacean shells, is proving to be a green innovation that can reduce waste while creating valuable products!
