Eicosanoids are derived from which acid?

• A. Fatty acid
• B. Arachidonic acid
• C. Linoleic acid
• D. Palmitic acid

Answer: (B)

Eicosanoids are biologically active lipids that play critical roles in various physiological processes, including inflammation, immunity, and regulation of blood pressure. They are specifically derived from arachidonic acid, which is a polyunsaturated fatty acid found in the phospholipid bilayer of cell membranes. Arachidonic acid serves as a key precursor for the synthesis of various eicosanoids, including prostaglandins, thromboxanes, and leukotrienes. These compounds exert potent effects on numerous cellular functions and contribute to the body's response to injury and disease. While fatty acids in general are essential components of eicosanoids, it is arachidonic acid that is the specific fatty acid from which these signaling molecules are synthesized. Other fatty acids like linoleic acid and palmitic acid do not directly lead to the formation of eicosanoids, although linoleic acid can be converted into arachidonic acid in the body through metabolic pathways.
