| fibrinopeptide a | Two small peptide chains removed from the n-terminal segment of the alpha chains of fibrinogen by the action of thrombin during the blood coagulation process. Each peptide chain contains 18 amino acid residues. In vivo, fibrinopeptide a is used as a marker to determine the rate of conversion of fibrinogen to fibrin by thrombin. (12 Dec 1998) |

| fibrinopeptide | <protein> Very negatively charged peptide fragments cleaved from fibrinogen by thrombin. Two peptides (A and B) are produced from each fibrinogen molecule. A: This is released as a part of the clotting process. Increased levels may be seen in DIC, lupus, cellulitis and leukaemia. (09 Oct 1997) |

| fibrinopeptide b | Two small peptide chains removed from the n-terminal segment of the beta chains of fibrinogen by the action of thrombin. Each peptide chain contains 20 amino acid residues. The removal of fibrinopeptides b is not required for coagulation. (12 Dec 1998) |
