Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3]
Protamine sulfate is a medication that is used to reverse the effects of heparin. [3] It is specifically used in heparin overdose, in low molecular weight heparin overdose, and to reverse the effects of heparin during delivery and heart surgery. [3] [4] It is given by injection into a vein. [3] The onset of effects is typically within five ...
Structure formula of one of the many sulfation patterns of the heparan sulfate subunit. Heparan sulfate (HS) is a linear polysaccharide found in all animal tissues. [1] It occurs in a proteoglycan (HSPG, i.e. Heparan Sulfate ProteoGlycan) in which two or three HS chains are attached in close proximity to cell surface or extracellular matrix proteins.
