In white blood cells, the main products of AA metabolism are leukotrienes, which are involved in inflammation [ 11, 12, 15 ].
What is the function of AA?
Most of the functions of AA is attributed to its conversion into other molecules – leukotrienes, prostaglandins, and more – through the action of enzymes (oxygenases) [ 5, 3 ]. AA is naturally produced in the body from another molecule (linoleic acid), and can also be ingested through different foods.
Does AA increase inflammation?
Although there is no consensus on whether high AA in take increases inflammation , certain populations may want to be cautious in their consumption [ 19, 4 ].
Why is arachidonic acid important?
Arachidonic acid is vital to the operation of the prostaglandin system. Prostaglandins are part of a class of substances called eicosanoids.
How do eicosanoids help with blood pressure?
These eicosanoids help support normal blood pressure by relaxing the arteries and blood vessels and decreasing blood lipids. They also decrease blood-clotting factors. Omega-6 fatty acids can produce both anti-inflammatory and/or inflammatory and vasoconstricting eicosanoids.
How many carbons are in eicosanoids?
The eicosanoids contain twenty carbons and include the prostaglandins (PG), prostacyclins (PGI2), thromboxanes (TX), leukotrienes (LT), and hydroxy acids. There are bad (pro-inflammatory) and good eicosanoids (anti-inflammatory) and they compete with each other. Two prostaglandins arachidonic acid is the substrate to are PGE2 and PGF2a.
What is the chemical messenger released by the body during intense weight training?

Also, anytime you have tissue injury, inflammation is involved in healing the wound.
What enzymes do eicosanoid cells compete for?
Also, they compete for cyclooxygenase and lipoxygenase, the enzymes necessary for eicosanoid synthesis.
Does exercise lower arachidonic acid?
Furthermore, in both animal and human studies it has been shown that exercise lowers the content of arachidnoic acid in skeletal muscle tissue. Therefore, there has been talk of arachidonic acid supplementation. The omega-6 and omega-3 fatty acid families form different eicosanoids with different activities.
Can linoleic acid be converted to arachidonic acid?
Linoleic acid can be converted into arachidonic acid. Arachidonic acid can be found mainly in the fatty parts of meats and fish (largely red meat), so vegetarians usually have lower levels of arachidonic acid in the body than those with omnivorous diets. There is a great deal of controversy about arachidonic acid.
What is arachidonic acid?

Which enzyme metabolizes arachidonic acid?
Lipoxygenase enzymes metabolise arachidonic acid to a group of noncyclised eicosanoids, the leukotrienes, some of which are also important inflammatory mediators. They are probably of particular importance in leucocyte-mediated aspects of chronic inflammation.
Is arachidonic acid an inflammatory agent?
Arachidonic acid is a polyunsaturated fatty acid covalently bound in esterified form in the cell membranes of most body cells. Following irritation or injury, arachidonic acid is released and oxygenated by enzyme systems leading to the formation of an important group of inflammatory mediators, the eicosanoids. It is now recognised that eicosanoid release is fundamental to the inflammatory process. For example, the prostaglandins and other prostanoids, products of the cyclooxygenase enzyme pathway, have potent inflammatory properties and prostaglandin E2 is readily detectable in equine acute inflammatory exudates. The administration of nonsteroidal anti-inflammatory drugs results in inhibition of prostaglandin synthesis and this explains the mode of action of agents such as phenylbutazone and flunixin. Lipoxygenase enzymes metabolise arachidonic acid to a group of noncyclised eicosanoids, the leukotrienes, some of which are also important inflammatory mediators. They are probably of particular importance in leucocyte-mediated aspects of chronic inflammation. Currently available non-steroidal anti-inflammatory drugs, however, do not inhibit lipoxygenase activity. In the light of recent evidence, the inflammatory process is re-examined and the important emerging roles of both cyclo-oxygenase and lipoxygenase derived eicosanoids are explored. The mode of action of current and future anti-inflammatory drugs offered to the equine clinician can be explained by their interference with arachidonic acid metabolism.
