An enzyme formed from prothrombin that converts fibrinogen to fibrin. (Dorland, 27th ed) EC 3.4.21.5.
Plasma protein involved in the coagulation of blood.
The key to thrombus (blood clot) formation. Thrombin is a proteolytic enzyme that cleaves fibrinogen into (molecular) pieces, which then spontaneously assemble themselves into fibrin, which forms a clot.
A substance which converts fibrinogen to fibrin and so coagulates blood.
A chemical substance in blood that causes it to begin to clot once it is no longer inside the body.
A substance (coagulation factor) that acts as an enzyme, converting the soluble protein fibrinogen to the insoluble protein fibrin in the final stage of blood coagulation. Thrombin is not normally present in blood plasma, being derived from an inactive precursor, prothrombin.
A n enzyme formed in coagulating blood from prothrombin, which reacts with soluble fibrinogen converting it to fibrin, which forms the basis of a blood clot.
An enzyme found in the liquid component of blood, known as plasma, that facilitates the conversion of fibrinogen into fibrin during the final phase of the clotting process.
The enzyme responsible for blood clotting when it’s outside the body.
