Qhov txawv ntawm Lutein thiab Zeaxanthin

Luteinlos ntawm Marigold paj nroj tsuag yog tsa nyob rau hauv ib tug pigment uas tau lug siv nyob rau hauv cov zaub mov additives, thiab tshuaj pigments. Lutein yog dav pom nyob rau hauv zaub, paj, txiv hmab txiv ntoo, thiab lwm yam nroj tsuag nyob rau hauv tej yam ntuj tso khoom, nyob rau hauv lub "Class carrot qeb ntawm" tsev neeg teeb meem, tam sim no paub tias muaj nyob rau hauv cov xwm, ntau tshaj 600 hom carotenoids, tsuas yog muaj txog 20 hom. nyob rau hauv tib neeg cov ntshav thiab cov ntaub so ntswg.

1. Nws tuaj yeem tiv thaiv peb qhov muag pom, thiab tseem ua lub luag haujlwm tseem ceeb tiv thaiv qhov chaw daj ntawm lub retina, thaum tsis muaj Lutein yuav ua rau macular degeneration thiab qhov muag tsis pom kev, ces qhov muag tsis pom kev;
2. Nrog rau kev ua haujlwm ntawm Antioxidant, nws tuaj yeem txo qhov kev pheej hmoo ntawm cov kab mob plawv, kab mob plawv, thiab mob qog noj ntshav;

Lutein thiab zeaxanthin yog ob qho tseem ceeb carotenoids feem ntau pom nyob rau hauv txiv hmab txiv ntoo thiab zaub. Lawv yog cov xanthophyll carotenoids, paub txog lawv cov xim daj rau xim liab. Cov tebchaw no ua lub luag haujlwm tseem ceeb hauv ntau yam txheej txheem lom neeg thiab tau kawm ntau ntxiv rau lawv cov txiaj ntsig kev noj qab haus huv.

Ua ntej, nws yog ib qho tseem ceeb kom nkag siab tias ob qho tib si lutein thiab zeaxanthin yog ib txwm tshwm sim sib txuas uas lub cev tsis tuaj yeem ua ke. Yog li ntawd, lawv yuav tsum tau txais los ntawm cov khoom noj los yog cov khoom noj khoom haus. Lub cev xaiv cov carotenoids nyob rau hauv cov ntaub so ntswg sib txawv, nrog lutein predominating nyob rau hauv lub qhov muag thiab zeaxanthin nyob rau hauv nruab nrab macula.

Qhov sib txawv tseem ceeb ntawm lutein thiabzeaxanthin uayog lawv cov qauv tshuaj thiab kev npaj ntawm ob daim ntawv cog lus. Lutein muaj cov mis molecular C40H56O2 thaum zeaxanthin muaj cov mis molecular C40H56O. Raws li txoj cai, ob lub tebchaw muaj 40-carbon qaum nrog oxygen atoms. Txawm li cas los xij, lutein muaj ob pawg hydroxyl (OH), thaum zeaxanthin muaj ib hydroxyl thiab ib pawg keto (C=O). Cov kev sib txawv me me no hauv lawv cov qauv ua rau muaj qhov sib txawv ntawm lawv lub cev thiab tshuaj lom neeg.

Ib qho ntawm qhov sib txawv tseem ceeb ntawm lutein thiab zeaxanthin yog lawv qhov nqus thiab qhov chaw nyob hauv lub cev. Hauv tib neeg kev noj haus, lutein feem ntau pom muaj nyob rau hauv cov nplooj ntsuab ntsuab xws li spinach thiab kale, thiab txiv hmab txiv ntoo xws li avocados thiab txiv kab ntxwv. Ntawm qhov tod tes, zeaxanthin pom muaj ntau dua hauv cov khoom noj xws li pob kws, txiv kab ntxwv peppers, thiab qe qe. Cov carotenoids nyob rau hauv cov khoom noj tshwj xeeb no muab lawv cov xim xim.

Nyob rau hauv cov nqe lus ntawm kev nqus, piv nrog zeaxanthin, lutein yog yooj yim absorbed los ntawm lub cev. Qhov no yog ib feem vim muaj cov pab pawg hydroxyl ntxiv hauv cov qauv lutein. Tsis tas li ntawd, lutein nyiam absorbed los ntawm macula ntawm lub qhov muag, pab tiv thaiv retina los ntawm oxidative puas los ntawm xiav lub teeb raug.

Ntawm qhov tod tes, zeaxanthin feem ntau pom muaj nyob hauv thaj chaw peripheral ntawm retina.

Lwm qhov sib txawv tseem ceeb ntawm lutein thiab zeaxanthin yog lawv cov haujlwm tshwj xeeb thiab cov txiaj ntsig hauv lub cev. Paub txog nws cov antioxidant zog, Lutein pab neutralize teeb meem dawb radicals thiab tiv thaiv hlwb los ntawm oxidative puas. Nws lub xub ntiag nyob rau hauv lub qhov muag muaj txiaj ntsig tshwj xeeb vim nws pab lim lub teeb xiav lub zog siab thiab txo qhov kev pheej hmoo ntawm hnub nyoog ntsig txog macular degeneration (AMD), qhov ua rau tsis pom kev thiab qhov muag tsis pom ntawm cov neeg laus. Zeaxanthin, ntawm qhov tod tes, xav tias muaj lub luag haujlwm tshwj xeeb hauv nruab nrab macula thiab ua lub luag haujlwm tseem ceeb hauv kev pom thiab qhov sib txawv rhiab heev. Nws yog concentrated nyob rau hauv fovea ntawm lub macula, lub luag hauj lwm rau ntse central tsis pom kev. Zeaxanthin tau xav tias yuav txhim kho qhov pom kev ua haujlwm los ntawm kev txo qis glare, nce qhov sib txawv, thiab txhim kho kev pom xim. Qee qhov kev tshawb fawb qhia tias zeaxanthin supplementation yuav pab tau cov tib neeg uas txo cov xim macular thiab cov tib neeg muaj kev pheej hmoo rau AMD. Thaum lutein thiab zeaxanthin muaj lub luag haujlwm tshwj xeeb, lawv kuj ua haujlwm sib koom ua ke los txhawb kev noj qab haus huv ntawm qhov muag. Cov tebchaw no ua raws li cov ntxaij lim dej ntuj, nqus cov teeb meem xiav thiab tiv thaiv cov qauv muag ntawm lub qhov muag los ntawm kev puas tsuaj oxidative. Lawv kuj pab tswj kev noj qab haus huv macular pigment ntom, uas yog qhov tseem ceeb rau kev pom kev pom kev zoo.

Ntxiv nrog rau lawv cov teebmeem ntawm qhov muag kev noj qab haus huv, lutein thiab zeaxanthin tau txuas rau ntau lwm yam txiaj ntsig kev noj qab haus huv. Ob leeg carotenoids tau txuas nrog txo kev pheej hmoo ntawm cov kab mob ntev xws li kab mob plawv thiab qee yam mob qog noj ntshav. Lawv cov khoom antioxidant ua lub luag haujlwm tseem ceeb hauv kev txo qhov mob, tiv thaiv DNA puas thiab tswj lub cev tiv thaiv kab mob.

Tsis tas li ntawd, lutein thiab zeaxanthin tau pom tias muaj kev tiv thaiv ntawm daim tawv nqaij noj qab haus huv. Los ntawm absorbing teeb meem UV hluav taws xob thiab neutralizing dawb radicals, cov carotenoids tuaj yeem pab tiv thaiv tshav ntuj, kev laus ntxov ntxov thiab kev puas tsuaj ntawm daim tawv nqaij los ntawm ntau lub hnub raug. Lawv feem ntau pom muaj nyob rau hauv cov khoom siv tshuaj pleev ib ce thiab suav nrog rau lawv cov peev xwm photoprotective. Hauv cov ntsiab lus, lutein thiab zeaxanthin yog ob qho tseem ceeb carotenoids uas ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa qhov muag thiab tiv thaiv ntau yam kab mob. Lutein tau yooj yim absorbed thiab pom feem ntau nyob rau hauv nruab nrab ntawm lub macula, thaum zeaxanthin yog concentrated nyob rau hauv lub periphery ntawm lub retina thiab muaj cuab kev pom tseeb ntawm lub zeem muag thiab qhov sib txawv rhiab heev. Ob lub carotenoids ua haujlwm sib koom ua ke los tiv thaiv lub qhov muag los ntawm kev puas tsuaj oxidative, txo qhov kev pheej hmoo ntawm AMD, thiab txhawb kev ua haujlwm ntawm kev pom tag nrho. Tsis tas li ntawd, lawv muaj cov tshuaj antioxidant uas txuas mus rau lwm cov ntaub so ntswg hauv lub cev, muab cov txiaj ntsig zoo rau kev mob plawv, tiv thaiv qog noj ntshav, thiab tiv thaiv tawv nqaij.
