What is Thrombin?
Thrombin is a serine protease enzyme that plays a crucial role in blood clotting. It is produced by the enzymatic cleavage of its inactive precursor prothrombin. Thrombin acts as a key mediator in the clotting cascade by catalyzing the conversion of soluble fibrinogen into insoluble fibrin strands, which forms a meshwork to create a blood clot. Also, thrombin activates other clotting factors and enhances platelet activation contributing to the amplification and stabilization of the clot.
Properties of Thrombin
The properties of thrombin are as follows:
- Active Enzyme: Thrombin is the active form of the prothrombin and acts as a serine protease enzyme.
- Fibrin Formation: One of the primary functions of the thrombin is to cleave fibrinogen a soluble protein into fibrin monomers.
- Positive Feedback Loop: Thrombin plays a role in amplifying the coagulation process by promoting the activation of the additional clotting factors including factors V, VIII, and XI.
- Platelet Activation: Thrombin also activates platelets promoting their aggregation at the site of the injury and further contributing to clot formation.
- Anticoagulant Regulation: Thrombin is involved in a complex balance between procoagulant and anticoagulant mechanisms.

Difference Between Thrombin and Prothrombin
The difference between thrombin and prothrombin lies in the fact that while prothrombin is an inactive precursor protein, thrombin in its activated form is crucial for blood clotting and wound healing. Thrombin and Prothrombin are key players in the blood clotting process known as hemostasis. Understanding the difference between thrombin and prothrombin is crucial for learning how blood clotting occurs and its effects on various health conditions. In this article, we will cover the differences between thrombin and prothrombin.
