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.

The correct statement about glycosaminoglycans is that it contains a high negative charge density which enables interaction with the aqueous environment.

Explanation:

The repeating disaccharide units of Glycosaminoglycans consist of N- acetylgalactosamine and uronic sugar.

Glycosaminoglycans are highly polar and attract water; they are therefore useful to the body as a lubricant or as a shock absorber.
