Arachidonic acid (AA) is an omega-6 polyunsaturated fatty acid. It competes for membrane space with EPA and DHA. AA creates pro-inflammatory eicosanoids which are believed to exacerbate dysfunction of immune, cardiovascular, retnal, bone, and central nervous systems. The omega-6 fatty acid EPA competes with AA for enzymatic action. This competition reduces the inflammatory response by EPA. EPA is crucial to provide anti-inflammatory effects by balancing the pro-inflammatory responses of AA. AA are not altogether "bad" fatty acids. They are "bad" with the chronically unbalanced American diet. The disproportionate EPA/AA ratio can lead to heightened risk for pro-inflammatory events that foster degenerative diseases.

  1. I think you need to proofread your summary. There were a couple sentences that were oddly written.
    Suggestions: Find a diagram of how EPA and DHA are arranged in membrane space. Find a diagram of how AA competes (wins) for that space. Find mechanisms for the enzymatic action and how that affects the anti-inflammatory effects of EPA. Does this competition of AA/EPA/DHA occur only in neurons?
