A protein that in humans plays a part in the forming of clots.
an albuminous substance existing in the blood, and in other animal fluids, which either alone or with fibrinoplastin or paraglobulin forms fibrin, and thus causes coagulation
U.S. National Library of Medicine
Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.
