<prompt> Choose the false statement regarding proteoglycans:Chondroitin sulfate is a ProteoglycanThey hold less amount of waterThey are made up of sugar and aminoacidsThey carry charge  <response>: Since the high fixed negative charge density of the proteoglycans allows them tohold enormous amounts of water. The amount of water depends on the amount of proteoglycans, which decreases with aging.
