since only heparin can , but only weakly at best , inhibit the activation of prothrombin in plasma depleted of both antithrombin iii and heparin cofactor ii , it is obvious that the anticoagulant effects of heparin , low molecular weight heparins , dermatan sulfate and heparan sulfate are mediated primarily by their catalytic effects on the antiprotease actions of antithrombin iii ( heparin , low molecular weight heparins and heparan sulfate ) and heparin cofactor ii ( dermatan sulfate ) .
