Thromboxanes are a type of eicosanoid derived from arachidonic acid, playing a crucial role in the process of hemostasis. They are produced primarily by platelets and have a significant impact on vascular tone, platelet aggregation, and smooth muscle contraction. Thromboxanes, particularly thromboxane A2 (TXA2), are known for their role in promoting platelet aggregation and vasoconstriction.
