Fibrin

Fibrin
The protein formed during normal blood clotting that is the essence of the clot.
* * *
An elastic filamentous protein derived from fibrinogen by the action of thrombin, which releases fibrinopeptides A and B from fibrinogen in the coagulation of blood; a component of thrombi, vegetations, and acute inflammatory exudates such as in diphtheria and lobar pneumonia. [L. fibra, fiber]

* * *

fi·brin 'fī-brən n a white insoluble fibrous protein formed from fibrinogen by the action of thrombin esp. in the clotting of blood

* * *

n.
the final product of the process of blood coagulation, produced by the action of the enzyme thrombin on a soluble precursor fibrinogen. The product thus formed (fibrin monomer) links up (polymerizes) with similar molecules to give a fibrous meshwork that forms the basis of a blood clot, which seals off the damaged blood vessel.

fi·brin (fiґbrin) the insoluble protein formed from fibrinogen by the proteolytic action of thrombin during normal clotting of blood; it forms the essential portion of the blood clot. fibrinous adj
