Web1 jan. 2011 · The heterogeneity of heparin’s chemical structure was increasingly appreciated, including its MW range, from 5,000 to 35,000 (Johnson and Mulloy 1976). However, the most important, and surprising, finding was described in 1976 by the groups of Lindahl (Höök et al. 1976 ) and Rosenberg (Lam et al. 1976 ), who used immobilised … Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. Since heparins depend on the activity of antithrombin, they are considered anticoagulants. Specifically it is also used in the treatment of heart attacks and unstable angina.
