Study Notes
Eicosanoids
- Eicosanoids are a family of biologically active substances derived from 20 carbon polyunsaturated fatty acids, such as arachidonic acid.
- Members of the eicosanoid family include prostaglandins, thromboxanes, leukotrienes, and epoxy-eicosatrienoic acids (EETs).
- Eicosanoids function as local hormones, synthesized and exerting their biological actions in the same tissue.
- They have physiological and pathological effects on various systems, including:
- Cardiovascular system
- Pulmonary system
- Reproductive system
- Digestive system
- Examples of their effects include:
- Inducing abortion or pregnancy ulcers
- Site-specific actions during shock and after injury
- Diverse functions, such as:
- Bronchoconstriction
- Bronchodilation
- Vasodilation
- Vasoconstriction
- Physiologically and pathologically, eicosanoids are local hormones, synthesized and exerting their action in a tissue, with actions usually discrete and related to the physiological demands of the tissue.
