Answer:
Chitin
Explanation:
Chitin is the polysaccharide that makes up the outer exoskeleton of many insects. It is a fibrous polymer, that is made up of chains of modified glucose molecules. It is comparable in structure to cellulose, which makes up the plant cell wall. In function, it is more similar to keratin or collagen, although these are proteins.
