Qhov Tseem Ceeb - Omega 3 vs Omega 6 Fatty Acids
Cov roj ntsha muaj ob kawg. Lawv yog cov carboxylic acid (-COOH) kawg, uas yog lub npe hu ua qhov pib ntawm cov saw thiab yog li tseem hu ua alpha, thiab methyl (CH3) kawg, uas yog hu ua tus Tsov tus tw ntawm cov saw thiab yog li ntawd kuj hu ua omega.. Lub npe ntawm fatty acid yog txiav txim los ntawm txoj hauj lwm ntawm thawj ob daim ntawv cog lus, xam los ntawm methyl kawg, uas yog Omega (ω-) los yog n-kawg. Noj qab nyob zoo omega 3 fatty acids thiab omega 6 fatty acids yog ib co ntawm cov tshuaj uas nrov tshaj plaws nyob rau hauv khw muag tshuaj thiab nutraceuticals. Feem ntau lawv yog muab los ntawm cov nroj tsuag thiab ntses roj. Lawv raug soj ntsuam zoo thiab tsis muaj kev phiv los ntawm kev phiv. Omega-3 fatty acids yog polyunsaturated fatty acids thiab lawv qhov kawg ob daim ntawv cog lus (C=C) muaj nyob rau ntawm peb carbon atom los ntawm qhov kawg ntawm cov carbon saw. Omega-6 fatty acids kuj yog polyunsaturated fatty acids tab sis, nyob rau hauv sib piv, lawv zaum kawg ob daim ntawv cog lus (C=C) muaj nyob rau ntawm lub thib rau carbon atom los ntawm qhov kawg ntawm cov carbon saw los yog methyl kawg. Qhov no yog qhov sib txawv tseem ceeb ntawm omega 3 thiab omega 6 fatty acids, thiab tsab xov xwm no tshawb txog txhua qhov sib txawv ntawm cov tshuaj thiab lub cev ntawm omega 3 thiab omega 6 fatty acids.
Omega 3 Fatty Acids yog dab tsi?
Omega-3 fatty acids yog polyunsaturated fatty acids (PUFAs) nrog ob daim ntawv cog lus (C=C) ntawm peb carbon atom los ntawm tus Tsov tus tw ntawm cov saw hlau. Muaj peb hom omega-3 fatty acids koom nrog hauv tib neeg lub cev, thiab lawv yog α-linolenic acid (ALA), eicosapentaenoic acid (EPA) thiab docosahexaenoic acid (DHA). Tib neeg tsis tuaj yeem tsim cov omega-3 fatty acids uas xav tau hauv lub cev, tab sis tuaj yeem nce cov saw luv omega-3 fatty acid, α-linolenic acid (ALA), los ntawm kev noj zaub mov txhua hnub thiab siv los tsim qhov tseem ceeb. long-chain omega-3 fatty acids xws li EPA thiab DHA. Txawm li cas los xij, kev muaj peev xwm ua kom cov saw ntev omega-3 fatty acids los ntawm ALA yuav raug txo qis nrog kev laus. Thaum cov zaub mov raug rau hauv qhov chaw, omega 3 unsaturated fatty acids raug oxidation thiab rancidity.

Omega 6 Fatty Acids yog dab tsi?
Omega-6 fatty acids yog polyunsaturated fatty acids (PUFAs) nrog qhov kawg ob daim ntawv cog lus (C=C) ntawm thib rau carbon atom los ntawm tus Tsov tus tw ntawm cov saw hlau. Lawv kuj yog tsev neeg ntawm pro-inflammatory thiab anti-inflammatory polyunsaturated fatty acids. Linoleic acid yog qhov luv tshaj chained omega-6 fatty acids, thiab nws yog ib qho ntawm ntau yam fatty acids uas tseem ceeb vim tib neeg lub cev tsis tuaj yeem tsim nws. Plaub yam khoom noj tseem ceeb xws li xibtes, taum pauv, rapeseed, thiab paj noob hlis yog cov nplua nuj ntawm omega 6 fatty acids. Lub paj thaum yav tsaus ntuj (O. biennis) kuj tsim cov roj uas muaj cov ntsiab lus siab ntawm γ-linolenic acid uas yog hom omega-6 fatty acid.

Qhov txawv ntawm Omega 3 thiab Omega 6 Fatty Acids yog dab tsi?
Definition:
Omega 3 fatty acids yog polyunsaturated fatty acids nrog qhov kawg ob daim ntawv cog lus (C=C) ntawm peb carbon atom los ntawm tus Tsov tus tw ntawm cov saw carbon.
Omega 6 fatty acids yog polyunsaturated fatty acids nrog rau qhov kawg ob daim ntawv cog lus (C=C) ntawm lub thib rau carbon atom los ntawm tus Tsov tus tw ntawm cov saw hlau.
Lwm Lub Npe:
Omega 3 fatty acids: ω-3 fatty acids, n-3 fatty acids
Omega 6 fatty acids: ω-6 fatty acids, n-6 fatty acids
Chemical Structure:
Omega 3 fatty acids: ALA yog ib qho tseem ceeb omega-3 fatty acid uas txhais tau tias yog 18: 3Δ9c, 12c, thiab 15c. Qhov no txhais tau hais tias cov saw hlau ntawm 18 carbons nrog 3 ob daim ntawv cog lus ntawm carbons khiav mus rau 9, 12, thiab 15. Txawm hais tias chemists suav los ntawm carbonyl carbon (qhia hauv xiav tooj), biologists thiab nutritionist suav los ntawm n (ω) carbon (qhia hauv liab tooj). Los ntawm n (ω) kawg (tus Tsov tus tw ntawm fatty acid), thawj ob daim ntawv cog lus zoo li qhov thib peb carbon-carbon daim ntawv cog lus, yog li ntawd, lub npe "n-3" los yog Omega 3 fatty acid.
Omega 6 fatty acids: Linoleic acid yog ib qho tseem ceeb omega-6 fatty acid uas txhais tau tias yog 18: 2Δ9c, 12c. Qhov no txhais tau hais tias cov saw hlau ntawm 18 carbons nrog 2 ob daim ntawv cog lus ntawm carbons khiav mus rau 9 thiab 12. Txawm hais tias chemists suav los ntawm carbonyl carbon (qhia hauv xiav tus lej), biologists thiab noj zaub mov suav los ntawm n (ω) carbon (qhia hauv cov lej liab). Los ntawm n (ω) kawg (tus Tsov tus tw ntawm fatty acid), thawj ob daim ntawv cog lus zoo li thib rau carbon-carbon daim ntawv cog lus, yog li lub npe "n-6" lossis Omega 6 fatty acid.

Cov peev txheej ntawm Omega 3 thiab Omega 6 Fatty Acids:
Omega 3 fatty acids: α-linolenic acid (ALA) muaj nyob rau hauv cov roj cog xws li walnut, edible noob, clary sage noob roj, algal roj, flaxseed roj, Sacha Inchi roj, Echium roj, thiab hemp roj.. Eicosapentaenoic acid (EPA) thiab docosahexaenoic acid (DHA) yog ob qho tib si muaj nyob rau hauv cov roj marine, marine algae, phytoplankton, ntses roj, krill roj, qe roj, thiab squid roj.
Omega 6 fatty acids: nplua nuj nyob rau hauv xibtes, taum pauv, rapeseed, yav tsaus ntuj primrose paj, cereal, thiab sunflower roj
He alth Aspects:
Omega 3 fatty acids yog txuam nrog ntau yam txiaj ntsig kev noj qab haus huv. Lawv yog;
- Txo kev pheej hmoo ntawm kev mob qog noj ntshav
- Tiv thaiv kab mob plawv, platelet aggregation thiab kub siab
- Pab txo qis LDL roj (cholesterol) phem thiab nce HDL cholesterol (cov roj cholesterol zoo)
- Lawv muaj cov haujlwm tiv thaiv kab mob thiab txo cov cim ntawm qhov mob hauv cov ntshav xws li C-reactive protein thiab interleukin 6
- Txo kev pheej hmoo ntawm mob caj dab rheumatoid
- Muab cov tshuaj ntxiv rau cov menyuam yaus autism thiab cov neeg mob Alzheimer's
- Kev loj hlob ntawm lub hlwb hauv cov menyuam yaus
Omega 6 fatty acids: Lawv muaj ob qho tib si pro-inflammatory thiab anti-inflammatory zog. Lawv tau muab tso rau hauv cov tshuaj siv tshuaj los tiv thaiv cov txheej txheem inflammatory hauv atherosclerosis, hawb pob, mob caj dab, kab mob vascular, thrombosis, txheej txheem tiv thaiv kab mob, thiab qog nqaij hlav. Tab sis ntau tshaj omega-6 fatty acids noj cuam tshuam nrog kev noj qab haus huv cov txiaj ntsig ntawm omega-3 rog vim tias lawv sib tw rau qhov sib npaug ntawm kev sib cuag nrog kev txwv cov enzymes. Ntxiv rau qhov ntawd, qhov ntau ntawm omega-6 rau omega-3 fatty acids nyob rau hauv cov zaub mov hloov lub cev lub cev nyob rau hauv cov ntaub so ntswg nyob rau hauv cov kev taw qhia ntawm lub pathogenesis ntawm ntau yam kab mob xws li pro-thrombotic, pro-inflammatory thiab pro-constrictive.
Hauv kev xaus, ob qho tib si omega 3 thiab omega 6 fatty acids muaj ntau lub luag haujlwm hauv tib neeg lub cev. Ntxiv nrog rau qhov tseem ceeb ntawm cov roj khaws cia, lawv tseem ua haujlwm tseem ceeb hauv lub tsev thaiv cov cell membranes thiab tswj cov txheej txheem inflammatory.
