nounan enzyme that acts on fibrinogen in blood causing it to clottype of:
Definition that contains thrombin
- heparin a polysaccharide produced in basophils (especially in the lung and liver) and that inhibits the activity of thrombin in coagulation of the blood; it (trade names Lipo-Hepin and Liquaemin) is used as an anticoagulant in the treatment of thrombosis and in heart surgery
- fibrin a white insoluble fibrous protein formed by the action of thrombin on fibrinogen when blood clots; it forms a network that traps red cells and platelets
- prothrombin a protein in blood plasma that is the inactive precursor of thrombin
- fibrinase in the clotting of blood thrombin catalyzes factor XIII into its active form (fibrinase) which causes fibrin to form a stable clot
- factor iii an enzyme liberated from blood platelets that converts prothrombin into thrombin as blood starts to clot
- fibrinopeptide peptide released from the amino end of fibrinogen by the action of thrombin to form fibrin during clotting of the blood
- liquaemin a polysaccharide produced in basophils (especially in the lung and liver) and that inhibits the activity of thrombin in coagulation of the blood; it (trade names Lipo-Hepin and Liquaemin) is used as an anticoagulant in the treatment of thrombosis and in heart surgery
- thrombokinase an enzyme liberated from blood platelets that converts prothrombin into thrombin as blood starts to clot
- factor x coagulation factor that is converted to an enzyme that converts prothrombin to thrombin in a reaction that depends on calcium ions and other coagulation factors
- hypothrombinemia a low level of prothrombin (factor II) in the circulating blood; results in long clotting time and poor clot formation and sometimes excessive bleeding; can result from vitamin K deficiency
