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.
