Answer:
The correct answer is E. Arachidonic acid is the raw material for synthesis of eicosanoids.
Explanation:
Arachidonic acid is an essential omega-6 fatty acid formed by a 20-carbon chain with four double bonds. The presence of double bonds causes this molecule to have several sites that can be oxidized, allowing the formation of different lipids with different biological activities.
Arachidonic acid is part of phospholipids in cell membranes, and is the precursor of eicosanoid biosynthesis. Arachidonic acid can be synthesized from linoleic acid, one of the essential fatty acids required by most mammals.
