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.
Synonyms : Fibrinopeptides A, A, Fibrinopeptide, A, Fibrinopeptides
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.
Fibroadenoma An adenoma containing fibrous tissue. It should be differentiated from ADENOFIBROMA which is a tumor composed of connective tissue (fibroma) containing glandular (adeno-) structures. (From Dorland, 27th ed)
Synonyms : Fibroadenomas
Fibrobacter A genus of gram-negative, anaerobic bacteria in the family Fibrobacteraceae, isolated from the human GASTROINTESTINAL TRACT.
