these observations prompted the investigation of the effects of four normal vessel wall glycosaminoglycans ( heparan sulfate , dermatan sulfate , chondroitin-4-sulfate , and chondroitin-6-sulfate ) on the intrinsic pathway generation of thrombin and factor xa and on the inactivation of thrombin and factor xa in plasma .
