Which is not a glycosaminoglycan?

Question

Quizplus · Accepted Answer

Chitin is not a glycosaminoglycan; it is a long-chain polymer of a N-acetylglucosamine, a derivative of glucose, and is a primary component of cell walls in fungi, the exoskeletons of arthropods, such as crustaceans and insects, and the scales of fish and amphibians. Glycosaminoglycans, on the other hand, are a type of long unbranched polysaccharides consisting of repeating disaccharide units that play a crucial role in the extracellular matrix of animal tissues.
