Answer:
True
Step-by-step explanation:
Eicosanoids are signaling molecules that are produced from fatty acids and act as local hormones (ex: prostaglandins, thromboxanes and leukotrienes). Eicosanoids are released immediately upon synthesis because they act as local hormones that function rapidly and locally to influence and modify physiological functions.
⇒ They are produced from arachidonic acid and EPA (eicosapentaenoic acid).
⇒ Synthesis of eicosanoids is induced by hormones and other stimuli.
⇒ They influence a wide range of physiological functions like blood pressure, blood clotting, inflammation, reproduction, etc.
⇒ They act rapidly in a paracrine or autocrine fashion, meaning they are released immediately after synthesis to act on nearby target cells. They are not stored.
⇒ They have short half-lives, usually only a few minutes in the circulation.
