All of the following are true regarding proteoglycans, EXCEPT:-: (A) Chondroitin sulfate is a glycosaminoglycan, (B) They hold less amount of water, (C) They are made up of sugar and aminoacids, (D) They carry negative charge
Answer is B. Chondroitin sulfate is a glycosaminoglycan -> option 1 is true Proteoglycan = core protein (Amino acid) + Glycosaminoglycan (sugar) -> option 3 is true Sulfate and acetyl groups confer negative charge to the amino acids -> option 4 is true As they are negatively charged, they can hold large amount of water, therefore -> option 2 is wrong.
