Question

Map sapling learning Proteoglycans are part of the extracellular matrix; they provide structure, viscosity and lubrication, and adhesiveness. They are composed of proteins conjugated to carbohydrate components called glycosaminoglycans. The glycosaminoglycan component makes up the majority of the mass of a proteoglycan (a) Which of the following are possible components of glycosaminoglycans? Select all that apply. N-acetylglucosamine negatively charged sulfate group -fructofuranose amylose (b) Determine which of the following statements about glycosaminoglycans are true. There is more than one true statement; select all the true statements. Because glycosaminoglycans consist of only two residues, they generally have low molecular weights. Hyaluronate and keratan sulfate are examples of glycosaminoglycans. Glycosaminoglycans are heteropolysaccharides composed of repeating disaccharide units. Dextran is an example of a glycosaminoglycan. Glycosaminoglycans are homopolysaccharides composed of repeating glucosamine or galactosamine residues

Explanation / Answer

a) the possible components of glycosaminoglycans are N-acetylglucosamine and negatively charged sulphate group.

b) the true statements are
