Web10 de ago. de 1993 · Abstract. This article reviews the significance of phospholipids in the haemostatic process. The plasma membranes of activated human blood platelets provide a catalytic phospholipid surface on which the "tenase" complex (factor IXa-factor VIIIa) and the "prothrombinase" complex (factor Xa-factor Va) can be assembled. WebSo, VWF binds to the to the platelets, binds to the collagen and immobilizes and builds up a platelet thrombus at the site of injury. And in this way, you prevent the loss of blood. So of course, there are many other hemostasis proteins that are involved in this process, but the platelet brick wall, if you like, would indeed be weak without
