Arachidonic Acid yog dab tsi?
Arachidonic acid (ARA) belongs rau Omega 6 ntev-chain polyunsaturated fatty acid.
Los ntawmARACov qauv, peb tuaj yeem pom nws muaj plaub carbon-carbon ob daim ntawv cog lus, cov pa roj carbon-oxygen ob daim ntawv cog lus, uas yog cov roj ntsha tsis txaus siab heev.
Puas yog ARA koom nrog Essential fatty acids?
Tsis yog, Arachidonic Acid tsis yog Essential fatty acids (EFAs).
Tsuas yog Alpha-linolenic acid (ib qho omega-3 fatty acid) thiab linoleic acid (ib qho omega-6 fatty acid) yog EFAs.
Txawm li cas los xij, Arachidonic acid yog tsim los ntawm Linoleic acid.Thaum peb lub cev tsis muaj linoleic acid, los yog muaj qhov tsis muaj peev xwm hloov linoleic acid rau ARA, peb lub cev yuav luv luv ntawm ARA, yog li AA tuaj yeem ua raws li qhov no.

Peb tuaj yeem nrhiav ARA nyob qhov twg hauv peb lub neej
Yog tias peb txheeb xyuas cov npe khoom muaj nyob rau hauv Baby mis hmoov, Arachidonic Acid (ARA) tuaj yeem pom tias yog ib qho ntawm cov khoom xyaw tseem ceeb rau kev txhim kho kev txawj ntse.
Koj yuav muaj lus nug, puas yog ARA tsuas yog qhov tseem ceeb rau cov menyuam mos?
Tsis Yog Tsis Muaj, ntau ARA cov tshuaj ntxiv rau hauv kev ua lag luam rau Kev Noj Qab Haus Huv thiab Kev Ua Si ntawm Kev Noj Qab Haus Huv Kev Noj Qab Haus Huv, pab txhawb cov leeg nqaij, lub zog, thiab kev txuag cov leeg thaum lub sijhawm kawm.
Puas yog Arachidonic Acid ua haujlwm rau lub cev?
Yog lawm.Lub cev tso siab rau ARA rau kev mob, ib qho kev tiv thaiv kab mob thiab tsim nyog los kho cov ntaub so ntswg puas.
Kev cob qhia lub zog yuav ua rau muaj kev mob hnyav, uas yog tsim nyog los tsim cov leeg loj.
Los ntawm daim duab hauv qab no, peb tuaj yeem pom ob lub prostaglandins tsim los ntawm ARA yog PGE2 thiab PGF2α.
Ib txoj kev tshawb fawb tau ua nrog cov leeg nqaij pob txha pom tau tias PGE2 nce protein ntau, thaum PGF2α txhawb kev tsim cov protein.Lwm cov kev tshawb fawb kuj pom PGF2α tuaj yeem ua rau cov leeg nqaij pob txha loj hlob.
Paub meej Arachidonic Acid Metabolism
Prostaglandin Synthesis:
Yuav luag txhua lub hlwb ntawm cov tsiaj nyeg tuaj yeem tsim cov prostaglandins thiab lawv cov khoom sib txuas (prostacyclins, thromboxanes thiab leukotrienes kuj hu ua eicosanoids).
Feem ntau ARA-derived eicosanoids tuaj yeem txhawb kev mob, tab sis qee qhov kuj ua los daws nws uas sib npaug los tiv thaiv.
Prostaglandins Physiological teebmeem raws li hauv qab no.
Prostaglandins yog synthesized los ntawm enzymes thiab reacts ntawm G-protein txuas receptors, thiab intracellularly kho los ntawm cAMP.
Arachidonic Acid thiab nws cov metabolism suav nrog Protaglandins (PG), Thromboxanes (TX) thiab Leukotrienes (LT)
ARA Kev Nyab Xeeb:
Khoom noj khoom haus tshiab:
2008/968/EC: Commission Kev Txiav Txim ntawm 12 Lub Kaum Ob Hlis 2008 tso cai tso rau hauv kev ua lag luam ntawm arachidonic acid-nplua nuj roj los ntawm Mortierella alpina ua cov khoom noj tshiab raws li Txoj Cai (EC) No 258/97 ntawm European Parliament thiab ntawm Pawg Sab Laj ( ceeb toom nyob rau hauv daim ntawv xov tooj C (2008) 8080)
GRAS
Kev txiav txim siab ntawm feem ntau lees paub tias muaj kev nyab xeeb (GRAS) cov xwm txheej ntawm arachidonic acid-nplua nuj roj ua cov khoom noj khoom haus rau cov menyuam mos daim ntawv thov.
New Resource Food
Tuam Tshoj Tsoom Fwv Teb Chaws pom zoo Arachidonic Acid ua Cov Khoom Noj Khoom Noj Tshiab.
Kev noj tshuaj arachidonic acid
Rau Cov Neeg Laus: Cov qib ARA tau txais nyob nruab nrab ntawm 210-250 mg / hnub hauv cov tebchaws tsim.
Rau kev tsim lub cev: nyob ib ncig ntawm 500-1,500 mg thiab noj 45 feeb ua ntej kev tawm dag zog
ARA txiaj ntsig:
Rau Baby
Lub Koom Haum Thoob Ntiaj Teb rau Kev Tshawb Fawb Txog Fatty Acids thiab Lipids (ISSFAL) Thawj Tswj Hwm - xibfwb Tom Brenna tau pom tias ARA muaj nyob rau hauv tib neeg cov kua mis ntawm qhov nruab nrab ntawm 0.47% ntawm tag nrho cov fatty acid.
Nyob rau hauv cov me nyuam mos thiab cov me nyuam yaus lub sij hawm, lub peev xwm ntawm tus me nyuam rau synthesize ARA yog tsawg, yog li rau cov me nyuam nyob rau hauv lub golden lub sij hawm ntawm lub cev kev loj hlob, muab ib tug tej yam ARA nyob rau hauv cov zaub mov yuav zoo dua rau kev loj hlob ntawm nws lub cev.Qhov tsis muaj ARA tuaj yeem ua rau muaj kev cuam tshuam loj heev rau kev loj hlob ntawm tib neeg cov ntaub so ntswg thiab lub cev, tshwj xeeb tshaj yog kev loj hlob ntawm lub hlwb thiab lub paj hlwb.
Rau Cov Neeg Laus
Kev tsim lub cev
Kev kawm ob qhov muag tsis pom kev tau ua rau 30 noj qab nyob zoo, cov txiv neej hluas nrog 2 xyoos ntawm kev cob qhia lub zog tsawg kawg rau yim lub lis piam.
Txhua tus neeg koom tau raug xa mus nqa ob daim ntawm cov gels uas muaj 1.5 grams tag nrho ntawm ARA lossis pob kws roj random.Cov neeg koom nrog siv cov softgel li 45 feeb ua ntej kev cob qhia, los yog thaum twg yooj yim rau cov hnub tsis kawm.
Cov txiaj ntsig ntawm DXA scan test qhia tau hais tias lub cev hnyav nce hauv ARA pawg nkaus xwb (+ 1.6 kilograms; 3%), pawg placebo yuav luag tsis muaj kev hloov pauv.
Ob pawg ntawm ob pawg ntawm cov leeg nqaij tuab tau nce ntau dua piv rau cov hauv paus, qhov nce ntau dua hauv AA pawg (8% vs. 4% nce; p = 0.08).
Rau cov rog rog, tsis muaj kev hloov pauv lossis qhov sib txawv.
kov yeej kev nyuaj siab
Cov kws tshawb fawb pom tias arachidonic acid tuaj yeem txo cov tsos mob ntawm kev nyuaj siab thiab thim rov qab lub hlwb cov cim tsis zoo.
Arachidonic acid kuj tau pom tias tuaj yeem kov yeej kev nyuaj siab zoo los ntawm kev txo cov ntshav.
Kho mob caj dab
Rau cov laus
Cov kws tshawb fawb tau ua ib qho kev sim rau nas, cov ntsiab lus raws li hauv qab no.
Hauv cov nas, qhov kev ua ntawm ib qho enzyme uas hloov linoleic acid rau arachidonic acid txo qis nrog kev laus, thiab kev noj zaub mov ntxiv rau arachidonic acid hauv cov nas muaj hnub nyoog zoo li txhawb kev paub, nrog P300 amplitude thiab latency kev ntsuam xyuas, uas tau muab luam tawm hauv 240 mg arachidonic. acid (ntawm 600 mg triglycerides) hauv lwm cov txiv neej noj qab haus huv.
Txij li thaum arachidonic acid yog tsawg tsim thaum lub sij hawm laus, supplementation nrog arachidonic acid tej zaum yuav muaj kev txawj ntse nce nyob rau hauv cov neeg laus.
Sab nyhuv
Txij li qhov sib npaug ntawm omega-3 thiab omega-6 fatty acids yog 1: 1 hauv peb lub cev.
Yog tias peb noj Arachidonic Acid ntau dhau lawm, peb lub cev Omega 6 fatty acid yuav siab dua Omega-3, peb yuav muaj teeb meem Omega-3 deficiency (qhuav tawv nqaij, nkig plaub hau, tso zis ntau zaus, insomnia, tev tes taw, teeb meem concentration, thiab kev xav hloov).
Omega-6 fatty acid ntau dhau yuav ua rau mob plawv, mob hawb pob, kab mob autoimmune, rog.
Txhawm rau kom paub tseeb tias koj yuav tsis ntsib qhov teeb meem no, thov noj Arachidonic acid raws li koj tus kws kho mob cov lus pom.
