WebbPlatelets contain a number of compounds involved in blood clotting. These are the so-called platelet (platelet) factors. The most important among them are: factor 3 (platelet thromboplastin). This is a phospholipid, which is released during the destruction of platelets and is used as a matrix for reactions in the I phase of coagulation.
