The 5-lipoxygenase enzyme metabolizes arachidonic acid in 5-hydroperoxycosatetraeneic acid (5-HPETE), which in turn is metabolized to several leukotrienes (i.e. In the chemical structure, arachidonic acid is a carboxylic acid with a chain of 20 carbons and four cis double bonds; the first double bond is found in the sixth carbon from the omega end. Arachidonic acid is a polyunsaturated fatty acid (PUFA) with 20 carbon atoms and four double bonds in the cis (Z) configuration.Since the first double bond, with respect to the methyl end, is between carbon 6 and 7, it is an omega-6 or n-6 polyunsaturated fatty acid, and in shorthand notation is referred to as 20:4n-6.AA also belongs to the group of very long chain fatty acids or VLCFAs, that is, fatty acids with 20 carbon atoms or more. Arachidonic acid also activates syntaxin-3 (STX-3), a protein involved in the growth and repair of neurons. Arachidonic acid (AA) metabolites have an important role in mediating vascular reactivity to various stimuli, affecting tissue perfusion and tissue supply. Some chemistry sources define 'arachidonic acid' to designate any of the eicosatetraenoic acids. Privacy Policy PLA2 is regulated by phosphorylation and calcium concentrations. Therefore, the safety of arachidonic acid supplementation in patients suffering from cancer, inflammatory, or other diseased states is unknown, and supplementation is not recommended. [35] The group does not recommend limiting this essential fatty acid. arachidonic acid. In cases of inflammatory diseases, the administration of arachidonic acid supplements is probably contraindicated. It has a role as a human metabolite, an EC 3.1.1.1 (carboxylesterase) inhibitor, a Daphnia galeata metabolite and a mouse metabolite. The anaerobic power of Wingate increased to a greater extent also in the arachidonic acid group (723.01 to 800.66 W) versus placebo (738.75 to 766.51 W). [39] This may result in a reduction in systemic inflammation. He is also involved in early neurological development. However, almost all those written in biology, medicine and nutrition limit the term to all-cis-5,8,11,14-eicosatetraenoic acid. When phosphorylation is combined with an influx of calcium ions, PLA2 is stimulated and can be translocated to the membrane to begin catalysis. Statistical trends were also observed in 1RM bench press (AA: 11.0 ± 6.2, P: 8.0 ± 8.0 kg, p = 0.20), average Wingate power (AA: 37.9 ± 10.0, P: 17.0 ± 24.0 W, p = 0.16), and the total work of Wingate (AA: 1292 ± 1206; P: 510 ± 1249 J, p = 0.087). Receptors that activate this pathway include: PLC may also be activated by MAP kinase. This effect is reinforced by the simultaneous administration of arachidonic acid with docosahexaenoic acid. Among other things, arachidonic acid helps to maintain hippocampal cell membrane fluidity. Arachidonic acid promotes repair and growth of skeletal muscle tissue by conversion to prostaglandin PGF2alpha during and after physical exercise. Furthermore, higher concentrations of ARA in muscle tissue may be correlated with improved insulin sensitivity. Those that are not essential are non-essential fatty acids. The group does not recommend limiting this essential fatty acid. Supplementation with arachidonic acid during resistance training promoted significant increases in relative maximum potency with other performance-related variables that approach significance. Arachidonic acid pathway is a central regulator of inflammatory response. However, the evidence is mixed. [29] There is evidence of significant alterations in the conversion of arachidonic acid to other bioactive molecules (overexpression or disturbances in the ARA enzyme cascade) in these conditions. Gastric acid and duodenal bile acids may contribute to carcinogenesis in BE through activation of this pathway. While another study suggests that arachidonic acid supplementation during the early stages of this disease may be effective in reducing symptoms and slowing the progression of the disease. [7] Since little or no arachidonic acid is found in common plants, such animals are obligate carnivores; the cat is a common example of having the inability to desaturate essential fatty acids. [8][9] A commercial source of arachidonic acid has been derived, however, from the fungus Mortierella alpina. Wingate anaerobic power increased to a greater extent in ARA group as well (723.01 to 800.66 W) vs. placebo (738.75 to 766.51 W). Arachidonic acid is not carcinogenic, and studies show that the level of the diet is not associated (positively or negatively) with the risk of cancer. Arachidonic acid is metabolized to proinflammatory and anti-inflammatory eicosanoids during and after the inflammatory response, respectively. [6], Arachidonic acid generated for signaling purposes appears to be derived by the action of group IVA cytosolic phospholipase A2 (cPLA2, 85 kDa), whereas inflammatory arachidonic acid is generated by the action of a low-molecular-weight secretory PLA2 (sPLA2, 14-18 kDa).[6]. Studies on arachidonic acid and the pathogenesis of Alzheimer's disease have shown mixed results, with one study of AA and its metabolites that suggests they are associated with the onset of Alzheimer's disease,[30] whereas another study suggests that the supplementation of arachidonic acid during the early stages of this disease may be effective in reducing symptoms and slowing the disease progress. Furthermore, higher concentrations of ARA in muscle tissue may be correlated with improved insulin sensitivity. Arachidonic acid is marketed as an anabolic bodybuilding supplement in a variety of products. These findings support the use of AA as an ergogenic. PLA2 is phosphorylated by a MAPK in Serine-505. [3] Its name derives from the New Latin word arachis (peanut), but it is important to note that peanut oil does not contain any arachidonic acid.[4]. PLA2, in turn, is activated by ligand binding to receptors, including: Furthermore, any agent increasing intracellular calcium may cause activation of some forms of PLA2.
