analysis of the glycosaminoglycan composition of the proteoglycan shows an increased amount of chondroitin sulfate , suggesting that the increased labeling per cell may be attributed to an augmented synthesis of chondroitin sulfate glycosaminoglycan on the core protein that also bears heparan sulfate , thus altering the proportions of these two glycosaminoglycans on this hybrid proteoglycan .
