Question

Quizplus · Accepted Answer

Chitin is a modified form of cellulose that has nitrogen atoms added to its glucose units to create a more durable structural material. The nitrogen atoms form hydrogen bonds with adjacent strands of chitin, forming a strong, resilient material that is commonly found in the exoskeletons of insects and crustaceans. The other options do not apply to the modification of chitin.
