for certain enzymes , such as acid beta-glycerophosphatase , alpha-galactosidase , acid lipase , lysozyme and phospholipase a2 , the ph-dependent behaviour obtained in the presence of heparin was quite different to that obtained with chondroitin sulphate , suggesting the existence of physicochemical characteristic factors playing a role in the intermolecular interaction for each of the sulphated glycosaminoglycans studied .
