Molecular model showing the structure of the blood clotting glycoprotein fibrinogen (factor I). The molecule consists of two sets of alpha, beta and gamma chains joined at a central nodule. Fibrinogen, which is synthesised by the liver, is converted by thrombin into fibrin during a cascade of complex reactions initiated by chemicals released by cells at injury sites. | |
