Qhov sib txawv tseem ceeb ntawm lutein thiab zeaxanthin yog tias lutein yog ib qho carotenoid molecule uas muaj nyob rau hauv feem ntau cov txiv hmab txiv ntoo thiab zaub, thaum zeaxanthin yog ib tug carotenoid molecule uas tam sim no nyob rau hauv feeb kom muaj nuj nqis nyob rau hauv feem ntau cov txiv hmab txiv ntoo thiab zaub.
Lutein thiab zeaxanthin yog ob lub carotenoid molecules. Lawv muaj nyob rau hauv ntau cov txiv hmab txiv ntoo thiab zaub. Lutein thiab zeaxanthin muaj cov haujlwm tseem ceeb ntawm lub cev. Lawv tuaj yeem muab kev tiv thaiv tiv thaiv kab mob qhov muag ntawm macular degeneration. Qhov xwm txheej no tau ua rau muaj kev txaus siab rau pej xeem hauv lawv cov txiaj ntsig kev noj qab haus huv thiab twb tau ua rau lawv suav nrog ntau yam tshuaj ntxiv.
Lutein yog dab tsi?
Lutein yog ib hom carotenoid molecule pom nyob rau hauv feem ntau txiv hmab txiv ntoo thiab zaub. Nws yog xanthophyll thiab ib qho ntawm 600 qhov tshwm sim carotenoid molecules. Nws tsuas yog tsim los ntawm cov nroj tsuag, zoo li lwm yam xanthophylls. Ntau cov lutein muaj nyob rau hauv cov nplooj ntsuab ntsuab xws li spinach, kale, thiab daj carrots. Nyob rau hauv cov nroj tsuag ntsuab, thaum lub sij hawm photosynthesis, xanthophylls pab hloov lub teeb lub zog thiab ua hauj lwm raws li ib tug non-photochemical quenching molecule los nrog triplet chlorophyll. Lutein kuj muaj nyob rau hauv qe qe thiab tsiaj rog. Tsis tas li ntawd, tsiaj tau txais lutein los ntawm kev siv cov nroj tsuag. Lutein muaj nyob rau hauv macula lutea ntawm retina hauv tib neeg. Nws yog absorbed rau hauv macula lutea los ntawm cov ntshav.
Daim duab 01: Lutein
Lutein isomeric nrog zeaxanthin. Nws txawv ntawm zeaxanthin vim muaj qhov tsawg dua ob daim ntawv cog lus hauv nws cov qauv. Lub teeb tshwj xeeb absorbing khoom ntawm lutein yog vim lub chromophore ntev ntawm conjugated ob daim ntawv cog lus (polyene saw). Lutein yog lipophilic molecule uas feem ntau insoluble hauv dej. Tsis tas li ntawd, nws tau pom tias lutein txo qhov kev pheej hmoo ntawm cov hnub nyoog ntsig txog macular degeneration thiab tiv thaiv kev txhim kho cataract. Lutein yog siv los ua zaub mov, tshuaj pleev xim, thiab kev noj zaub mov ntxiv. Tsis tas li ntawd, nws kuj yog siv rau hauv cov tshuaj, hauv cov zaub mov tsiaj, thiab hauv tsiaj thiab ntses pub. Cov ntawv thov tshiab dua suav nrog cov khoom siv qhov ncauj thiab tshuaj pleev ib ce rau kev noj qab haus huv ntawm daim tawv nqaij.
Zeaxanthin yog dab tsi?
Zeaxanthin yog ib qho carotenoid molecule uas tam sim no tsuas yog nyob rau hauv feeb kom muaj nuj nqis nyob rau hauv feem ntau txiv hmab txiv ntoo thiab zaub. Nws yog synthesized nyob rau hauv cov nroj tsuag thiab ib co microorganisms. Cov xim no muab paprika, pob kws saffron, goji, thiab ntau lwm cov nroj tsuag lawv cov xim xim. Nws kuj muab qee cov microbes lawv cov yam ntxwv xim thiab. Xanthophylls zoo li zeaxanthin muaj nyob rau hauv ntau tshaj plaws nyob rau hauv nplooj ntawm feem ntau ntsuab nroj tsuag. Nws kuj tseem siv rau hauv lub voj voog xanthophyll.
Daim duab 02: Zeaxanthin
Zeaxanthin yog ib qho ntawm ob lub xanthophyll carotenoid molecules muaj nyob rau hauv lub retina ntawm tib neeg lub qhov muag. Kev tshawb fawb tsis ntev los no tau qhia tias zeaxanthin txo qis kev pheej hmoo ntawm cov hnub nyoog ntsig txog macular degeneration thiab tiv thaiv kev txhim kho cataract. Tsis tas li ntawd, nws kuj yog siv los ua khoom noj khoom haus thiab cov khoom noj xim.
Dab tsi yog qhov zoo sib xws ntawm Lutein thiab Zeaxanthin?
- Lutein thiab zeaxanthin yog ob lub carotenoid molecules.
- Ob leeg yog isomers thiab muaj cov tshuaj formula C40H56O2.
- Lawv yog cov tshuaj tua kab mob muaj zog.
- Ob leeg pom muaj ntau yam txiv hmab txiv ntoo thiab zaub.
- Ob leeg siv rau hauv lub voj voog xanthophyll.
- Hauv photosynthesis, ob qho tib si pab hloov lub teeb lub zog thiab ua haujlwm ua cov tshuaj tsis muaj yees duab quenching molecule los cuam tshuam nrog triplet chlorophyll.
- Ob leeg muaj nyob hauv tib neeg retina.
- Lawv tiv thaiv tib neeg lub qhov muag los ntawm kev txo cov macular degeneration thiab tiv thaiv kab mob cataracts.
- Lawv kuj siv los ua khoom noj khoom haus ua lag luam.
Qhov txawv ntawm Lutein thiab Zeaxanthin yog dab tsi?
Lutein yog ib hom carotenoid molecule uas muaj nyob rau hauv feem ntau cov txiv hmab txiv ntoo thiab zaub, thaum zeaxanthin yog ib tug carotenoid molecule uas tam sim no tsuas yog nyob rau hauv feeb kom muaj nuj nqis nyob rau hauv feem ntau txiv hmab txiv ntoo thiab zaub. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lutein thiab zeaxanthin. Tsis tas li ntawd, lutein muaj 10 ob daim ntawv cog lus hauv cov qauv, thaum zeaxanthin muaj 11 ob daim ntawv cog lus hauv cov qauv.
Cov hauv qab no qhia txog qhov sib txawv ntawm lutein thiab zeaxanthin hauv daim ntawv qhia rau kev sib piv ntawm ib sab.
Summary – Lutein vs Zeaxanthin
Lutein thiab zeaxanthin yog ob lub carotenoid molecules. Ob leeg yog isomers thiab muaj cov tshuaj formula C40H56O2 Qhov sib txawv tseem ceeb ntawm lutein thiab zeaxanthin yog tias lutein feem ntau pom muaj nyob rau hauv feem ntau txiv hmab txiv ntoo thiab zaub, thaum zeaxanthin tsuas yog nyob rau hauv feeb kom muaj nuj nqis nyob rau hauv feem ntau txiv hmab txiv ntoo thiab zaub.
