Factor Xa

Factor Xa is an important protein in the blood clotting process. It acts as an enzyme that helps convert prothrombin, another protein, into thrombin. Thrombin is essential for turning fibrinogen into fibrin, which forms a mesh that traps blood cells and creates a stable blood clot. This process is crucial for stopping bleeding when injuries occur. Factor Xa plays a key role in both normal clotting and in certain medical conditions, making it a target for specific blood-thinning medications used to prevent clots in conditions like atrial fibrillation or after certain surgeries.
