| Arachidonic acid Usage And Synthesis |
| Description |
Arachidonic acid belongs to a kind of polyunsaturated omega-6 fatty acid, which is highly biologically relevant. It is abundantly distributed in brain, muscles and liver. It is the precursor for all prostaglandins, thromboxanes, and leukotrienes. Most cellular arachidonic acid is esterified in the membrane phospholipids. It is an important second messenger of cellular signalling participating in the regulation of signaling enzymes including PLC-γ, PLC-δ, and PKC-α, -β, and -γ isoforms. In addition, arachidonic acid acts as key inflammatory intermediate as well as avasodilator. Generally, the body can synthesize the arachidonic acid through linoleic acid. However, upon linoleic acid deficiency, it is necessary to supplement arachidonic acid from the diets. Food sources of arachidonic acid include meat, eggs and some fishes. Alternatively, we can also have arachidonic acid supplements. |

| Description |
Arachidonic acid (AA, sometimes ARA) is a polyunsaturated omega-6 fatty acid 20:4(ω-6). It is the counterpart to the saturated arachidic acid found in peanut oil, (L. arachis – peanut.). |
| Chemical Properties |
In chemical structure, arachidonic acid is a carboxylic acid with a 20-carbon chain and four cis-double bonds; the first double bond is located at the sixth carbon from the omega end.
Some chemistry sources define 'arachidonic acid' to designate any of the eicosatetraenoic acids. However, almost all writings in biology, medicine and nutrition limit the term to all-cis-5,8,11,14- eicosatetraenoic acid. |
| Chemical Properties |
liquid |
| Uses |
An unsaturated omega-6 fatty acid constituent of the phospholipids of cell membranes |
| Uses |
Arachidonic Acid is an essential fatty acid and a precursor in the biosynthesis of prostaglandins, thromboxanes, and leukotrienes. Arachidonic Acid occurs in liver, brain, glandular organs, and depot fats of animals, in small amounts in human depot fats, and Arachidonic Acid is also a constituent of animal phosphatides. |
| Uses |
arachidonic acid is an ingredient with skin-smoothing, emollient, and healing properties. Arachidonic acid is an omega-6 essential fatty acid naturally occurring in the skin and considered critical for appropriate skin metabolism. It is a constituent of vitamin F. |
| Definition |
ChEBI: A long-chain fatty acid that is a C20, polyunsaturated fatty acid having four (Z)-double bonds at positions 5, 8, 11 and 14. |
| Biological Activity |
Endogenous free fatty acid released from phospholipids by phospholipase A 2 . Important cellular signaling mediator and precursor of eicosanoids. Metabolized by lipoxygenases, cyclooxygenases and cytochrome P450 monooxygenases. |
| Safety Profile |
Poison by intravenous route.Experimental reproductive effects. Mutation datareported. When heated to decomposition it emits acridsmoke and irritating fumes. |
| Carcinogenicity |
In vitro and in vivo studies indicate that inhibition of arachidonic acid metabolism inhibits the growth of malignant cells, including head and neck squamous cell carcinoma, and implicates arachadonic acid in facilitating the metastasis of these tumor cells. Arachidonic acid reaction with cyclooxygenase and lipoxygenases yield eicosanoids that can mediate prostate cancer proliferation and enhance both tumor vascularization and metastasis. Cytochrome P450 arachidonic acid epoxygenases promote cell proliferation and inhibit apoptosis in endothelial cells. |
