All glycosaminoglycans contain which of the following?

Question

Quizplus · Accepted Answer

All glycosaminoglycans contain a repeating disaccharide unit composed of an amino sugar (either glucosamine or galactosamine) and a uronic acid (either glucuronic acid or iduronic acid) that carries a variable number of sulfated hydroxyl groups. The amino sugar contains an amine group that can be either acetylated or sulfated. Therefore, option D is the correct answer. A, B, and C are incorrect as not all glycosaminoglycans contain a sulfate ester, the glycosidic bond mentioned is specific to heparan sulfate, and not all of them contain a carboxylate.
