WebHeparin is a highly sulphated glycosaminoglycan with the ability to bind a very wide range of biomolecules including: DNA binding proteins such as initiation factors, elongation factors, restriction endonucleases, DNA ligase, DNA and RNA polymerases. Serine protease inhibitors such as antithrombin III, protease nexins. WebUnfractionated heparin inhibits thrombin (factor IIa) by forming a ternary complex. The inhibitory effect of LMW heparins on thrombin is variable, with longer products such as tinzaparin having greater inhibition than the shorter products such as enoxaparin. All heparins and fondaparinux efficiently inactivate factor Xa.
