Which of these are possible components of glycosaminoglycans?

a) amylose uronic acid

b) β‑d‑fructofuranose

c)n‑acetylgalactosamine

determine which statements about glycosaminoglycans are true:

1.chondroitin sulfate and heparin are examples of glycosaminoglycans. because glycosaminoglycans consist of only two residues, they generally have low molecular weights.

2.glycosaminoglycans contain a high negative charge density, which enables interaction with the aqueous environment.

3.cellulose is an example of a glycosaminoglycan.

4.glycosaminoglycans are homopolysaccharides composed of repeating glucosamine or galactosamine residues.
