Fibrin''' === Fibrin is an insoluble protein that plays a key role in blood clot formation (coagulation). It is derived from fibrinogen, a soluble plasma protein, through the action of thrombin. ==== '''1. Formation of Fibrin''' ==== * '''Conversion of Fibrinogen to Fibrin:''' ** Thrombin (Factor IIa) converts fibrinogen into fibrin monomers. ** These monomers polymerize to form a fibrin network. * '''Stabilization of Fibrin Clot:''' ** Factor XIIIa (fibrin-...")
