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 components of glycosaminoglycans is N- acetylgalactosamine option C.

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.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
