Definition of thrombin in English: thrombinnoun ˈθrɒmbɪnˈθrɑmbən mass nounBiochemistry An enzyme in blood plasma which causes the clotting of blood by converting fibrinogen to fibrin. Example sentencesExamples - Protective mechanisms prevent thrombin and other procoagulant enzymes from forming in healthy intact blood vessels.
- Fibrinogen is modified by thrombin to produce fibrin monomers that are the primary constituent of the fibrin clot.
- The thrombin cleaves fibrinogen to an active monomer that polymerizes to form a fibrin meshwork.
- Big, long, expensive programs against enzymes like elastase and thrombin went on year after year, but no one could get the things to quite work well enough.
- In addition to its role in activation of fibrin clot formation, thrombin plays an important regulatory role in coagulation.
- The blood-clotting cascade ends in the formation of a substance that converts a blood protein called prothrombin into the protein thrombin, which actually forms the substance of the blood clot.
Origin Late 19th century: from Greek thrombos 'blood clot' + -in1.
