So the proteolytic cleavage of fibrinogen exposes regions of the structure that can interact with other fibrin monomers. Therefore fibrin monomers spontaneously aggregate to form long fibers structures called fibrin. So we have the aggregation of these fibrin monomers because now these sections here are basically exposed and these sections found on the alpha unit, the red one can basically interact and fit into these holes found on the green structures, those gamma units. And so this is basically what we form. So we have these red structures found on the alpha that interact with the blue hole, the green structures, the holes found in the green structures, those gamma structures. And so we form this mesh like structure, this meshlike network of fiber monomers and we call this entire structure fiber or blood clots.
