Question

Quizplus · Accepted Answer

Chitin and cellulose are both composed of long chains of glucose molecules, linked together by beta 1-4 glycosidic bonds. However, in chitin, every other glucose molecule is replaced by a nitrogen-containing group called a N-acetylglucosamine. This substitution gives chitin its unique properties and makes it chemically similar to cellulose.
