Arachidonic acid (AA) yog polyunsaturated omega-6 fatty acid. Nws yog ib qho tseem ceeb fatty acid, txhais tau hais tias tib neeg lub cev tsis tuaj yeem tsim nws thiab yuav tsum tau txais los ntawm kev noj haus. Arachidonic acid plays lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem physiological thiab tseem ceeb tshwj xeeb rau cov qauv thiab kev ua haujlwm ntawm cov cell membranes.
Nov yog qee cov ntsiab lus tseem ceeb txog arachidonic acid:
Qhov chaw:
Arachidonic acid feem ntau pom muaj nyob rau hauv cov khoom noj tsiaj, tshwj xeeb tshaj yog nyob rau hauv cov nqaij, qe, thiab cov khoom noj siv mis.
Nws tseem tuaj yeem ua ke hauv lub cev los ntawm kev noj zaub mov ua ntej, xws li linoleic acid, uas yog lwm yam tseem ceeb fatty acid uas pom hauv cov roj cog.
Biological Functions:
Cell Membrane Structure: Arachidonic acid yog ib qho tseem ceeb ntawm cov cell membranes, pab txhawb rau lawv cov qauv thiab fluidity.
Inflammatory Response: Arachidonic acid ua haujlwm ua ntej rau kev sib txuas ntawm cov khoom siv hluav taws xob hu ua eicosanoids. Cov no suav nrog prostaglandins, thromboxanes, thiab leukotrienes, uas ua lub luag haujlwm tseem ceeb hauv lub cev tiv thaiv kab mob thiab tiv thaiv kab mob.
Neurological Function: Arachidonic acid yog tam sim no nyob rau hauv siab concentrations nyob rau hauv lub hlwb thiab yog ib qho tseem ceeb rau txoj kev loj hlob thiab kev ua hauj lwm ntawm lub hauv paus paj hlwb.
Cov leeg nqaij loj hlob thiab kho: Nws koom nrog kev tswj hwm ntawm cov leeg nqaij protein synthesis thiab tuaj yeem ua lub luag haujlwm hauv kev loj hlob thiab kho cov leeg nqaij.
Eicosanoids thiab Inflamation:
Kev hloov pauv ntawm arachidonic acid rau eicosanoids yog txheej txheem nruj nruj. Eicosanoids muab tau los ntawm arachidonic acid tuaj yeem muaj ob qho tib si pro-inflammatory thiab anti-inflammatory teebmeem, nyob ntawm seb hom eicosanoid tshwj xeeb thiab cov ntsiab lus uas nws tsim.
Qee cov tshuaj tiv thaiv kab mob, xws li nonsteroidal anti-inflammatory tshuaj (NSAIDs), ua haujlwm los ntawm inhibiting enzymes koom nrog hauv kev sib txuas ntawm qee yam eicosanoids tau los ntawm arachidonic acid.
Kev xav txog kev noj haus:
Thaum arachidonic acid yog qhov tseem ceeb rau kev noj qab haus huv, kev noj ntau dhau ntawm omega-6 fatty acids (xws li arachidonic acid precursors) txheeb ze rau omega-3 fatty acids hauv kev noj zaub mov tau cuam tshuam nrog kev tsis sib haum xeeb uas yuav ua rau muaj mob hnyav.
Ua tiav qhov sib npaug ntawm omega-6 rau omega-3 fatty acids hauv kev noj zaub mov feem ntau suav hais tias tseem ceeb rau kev noj qab haus huv tag nrho.
Ntxiv:
Cov tshuaj arachidonic acid muaj, tab sis nws yog ib qho tseem ceeb uas yuav tsum tau ua kom zoo ntxiv nrog kev ceev faj, vim tias kev noj ntau dhau tuaj yeem cuam tshuam rau kev mob thiab kev noj qab haus huv tag nrho. Ua ntej xav txog kev noj tshuaj ntxiv, nws raug nquahu kom sab laj nrog tus kws kho mob.
Hauv cov ntsiab lus, arachidonic acid yog ib qho tseem ceeb ntawm cov cell membranes thiab koom nrog ntau yam physiological txheej txheem, nrog rau kev mob thiab kev tiv thaiv kab mob. Thaum nws yog ib qho tseem ceeb rau kev noj qab haus huv, kev tswj kom muaj kev sib npaug ntawm omega-6 thiab omega-3 fatty acids yog qhov tseem ceeb rau kev noj qab haus huv tag nrho. Raws li nrog rau txhua yam kev noj haus, tus neeg xav tau kev pab thiab kev noj qab haus huv yuav tsum raug txiav txim siab, thiab cov lus qhia los ntawm cov kws kho mob yuav tsum tau nrhiav thaum tsis ntseeg.
