Prothrombin

Meaning

Prothrombin, scientifically designated as Factor II, is a crucial vitamin K-dependent glycoprotein synthesized in the liver, functioning as an inactive precursor protein within the complex cascade of blood coagulation. This zymogen circulates in the bloodstream in its dormant state, awaiting specific enzymatic activation to transform into thrombin, which is the direct catalyst for clot formation, thereby ensuring the integrity of the vascular system.
