What is the function of eicosanoids?

Eicosanoids are signaling molecules derived from fatty acids, primarily arachidonic acid, and play crucial roles in various physiological processes. They are involved in inflammation, immune responses, and regulation of blood flow, as well as functions in the central nervous system. Eicosanoids include prostaglandins, thromboxanes, and leukotrienes, each with specific roles in mediating cellular communication and responses to injury or stress. Overall, they are essential for maintaining homeostasis and responding to physiological challenges.
