Arachidonic Acid yog polyunsaturated omega -6 fatty acid 20:4 (ω-6). Insen Arachidonic Acid cov khoom yog ntuj fermented los ntawm Mortierella alpina. Nws yog dav siv rau cov khoom noj khoom haus thiab khoom noj khoom haus, tshwj xeeb tshaj yog rau cov menyuam mos mis thiab cov tshuaj ntxiv.
Cov txiaj ntsig ntawm Arachidonic Acid:
1. Tswj lub siab excitability:
Cov kev tshawb fawb tshiab tshaj plaws tau tshaj tawm tias arachidonic acid thiab nws cov metabolites xws li LTC4 tuaj yeem ua rau lub plawv haematopin-zoo li K ntxiv rau channel ua ke nrog G protein nyob rau hauv ib qho kev ywj pheej receptor, thiab tswj lub plawv excitation nyob rau hauv physiological thiab pathological mob.
2. Koom nrog hauv neuroendocrine:
Arachidonic acid tuaj yeem txhawb kev tso tawm ntawm cov qog pituitary anterior, placenta thiab mast hlwb, thiab koom nrog kev tswj hwm ntawm ntau yam tshuaj hormones thiab neuropeptides hauv ntau cov ntaub so ntswg neuroendocrine, xws li oxytocin, vasopressin, insulin thiab glucagon, thiab lwm yam.
3. Lub luag haujlwm ntawm kev txhawb nqa cell faib:
Arachidonic acid thiab nws cov metabolites tuaj yeem txhawb kev faib tawm ntawm tes, thiab nws cov metabolites muaj cov nyhuv no hauv cov leeg nqaij, fibroblasts, thiab lymphocytes.
4. Inhibition ntawm platelet aggregation:
Arachidonic acid thiab nws cov metabolites ua rau vasodilation. Vascular endothelial hlwb yog ze ze rau arachidonic acid enzyme, uas tuaj yeem tso tawm vasodilation yam, so vascular du nqaij, thiab dilate cov hlab ntsha nyob rau hauv qee yam stimuli.
Daim ntawv thov tseem ceeb ntawm arachidonic acid:
1. Cov khoom noj khoom haus tshiab tshiab
Vim tias qhov kev ua desaturase qis hauv cov menyuam mos thiab cov menyuam yaus, txawm tias lawv noj cov linoleic acid txaus, lawv tsis tuaj yeem tsim cov arachidonic acid uas xav tau rau kev loj hlob thiab kev loj hlob.
Lub fetus tau txais thiab khaws cov arachidonic acid los ntawm leej niam los ntawm cov placenta, thiab tau txais arachidonic acid los ntawm cov kua mis thiab cov zaub mov tom qab yug me nyuam. Yog hais tias theem ntawm arachidonic acid nyob rau hauv niam cov ntshav yog tsawg los yog cov khoom noj muaj txwv thaum lub sij hawm pub mis, nws yuav ua rau arachidonic acid deficiency nyob rau hauv fetuses thiab cov me nyuam mos. Raws li qhov tseeb tias arachidonic acid yog ib qho tseem ceeb rau tib neeg txoj kev loj hlob thaum ntxov thiab muaj kev cuam tshuam tshwj xeeb rau kev loj hlob ntawm lub paj hlwb thiab lub paj hlwb ntawm fetuses thiab cov me nyuam mos, arachidonic acid feem ntau yog siv hauv cov khoom noj khoom haus rau cov poj niam cev xeeb tub thiab cov khoom noj mis. rau me nyuam mos.
Arachidonic acid yog ib qho tseem ceeb ntawm cov kua mis. Ntau xyoo ntawm kev tshawb fawb nyob rau hauv ntau lub teb chaws nyob rau hauv lub ntiaj teb no tau pom tias qhov nruab nrab muaj pes tsawg leeg ntawm cov kua mis nyob rau hauv txawv cheeb tsam yog sib xws, thiab cov ntsiab lus ntawm arachidonic acid yog nyob nruab nrab ntawm {{0}}.5 feem pua thiab 0.7 feem pua. Nws muaj ntau dua nyob rau hauv cov mis nyuj thiab yuav luag tsis muaj nyob rau hauv nyuj cov mis nyuj.
2. Ntses noj nplua nuj nyob rau hauv arachidonic acid
Hauv 20 xyoo dhau los, cov kev xav tau ntawm cov ntses tseem ceeb fatty acids tau kawm ntau hauv tsev thiab txawv teb chaws. Nws feem ntau ntseeg tau tias cov ntses muaj qhov xav tau qeeb rau arachidonic acid, uas tuaj yeem ua tau raws li arachidonic acid uas muaj nyob rau hauv pub (ntses nqaij thiab ntses roj), tab sis nyob rau theem tshwj xeeb ntawm cov ntses lub neej voj voog, cov qib siab yuav xav tau Arachidonic acid. kom acclimate.
Arachidonic acid muaj txiaj ntsig zoo rau cov ntses loj hlob, muaj sia nyob thiab tiv thaiv kev ntxhov siab; txhawb nqa ntses yug me nyuam, txhim kho cov qe, phev thiab cov noob zoo; tswj kev tiv thaiv kab mob ntawm cov ntses. Yog li ntawd, ntses pub nplua nuj nyob rau hauv arachidonic acid muaj kev lag luam dav dav.
