A type of eicosanoid which causes clotting of blood and increases stickiness of platelets. The thromboxane produced from omega-3 fatty acids is devoid of any activity.

A group of compounds biochemically related to the prostaglandins and initially made from fatty acids. Different fatty acids lead to different thromboxanes, and each type of thromboxane has a different action. For instance, thromboxane B-2 can induce clot formation.

Thromboxane is a member of the family of lipids known as eicosanoids. It is produced in platelets by thromboxane-A synthase from the endoperoxides produced by the cyclooxygenase (COX) enzyme from arachidonic acid.
