1. Isakhiwo samakhemikhali
Ifomula yamangqamuzana e-lutein yi-C40H56O2, isisindo se-molecular esihlobene singu-568.85 kanye ne-CAS No{4}}; I-lutein iyi-dihydroxy carotenoid equkethe indandatho ye-ionone.
I-molecular formula ye-lutein ester yi-C72H116O4, futhi isisindo samangqamuzana esihlobene singu-1045.71.
I-Lutein ester iyisakhiwo se-fatty acid ye-lutein futhi inesisindo esikhulu samangqamuzana.
I-Lutein ester iyi-carotenoid fatty ester ester. Isakhiwo esikhulu sakhiwe-izindandatho zekhabhoni{1}}ezingamalungu ayisithupha axhunywe iketango elide elinebhondi ephindwe kabili ehlanganisiwe equkethe ama-athomu ekhabhoni ayishumi nesishiyagalombili. I-Lutein ester ingahlukaniswa nge-trans- Ifomula kanye ne-cis-i-lutein esters, iningi lakhona elitholakala ezitshalweni zemvelo kukho konke{5}}ukucushwa kwe-trans molecular.
2. Inqubo
I-Lutein ester itholakala ngokukhishwa nge-organic solvent ezimbalini ze-marigold, bese i-lutein ester iphinde ifakwe i-saponified ngama-alkali reagents, futhi isakhiwo se-fatty acid -R esakhiweni se-lutein ester siguqulelwa ku--OH, okuba yi-Lutein. I-Lutein ester iwumkhiqizo omaphakathi wokuthola i-lutein, ephinde ikhombise ngokungaqondile ukuthi ingxenye eyenzeka ngokwemvelo ku-marigold i-lutein ester, hhayi i-lutein.
3. Umthombo
Lolu hlobo lwe-lutein alukho emvelweni. Isibonelo, i-lutein ikhona mahhala-ifomu elingaqinisiwe emifino eluhlaza nezithelo, njenge-broccoli, ubhontshisi oluhlaza, uphizi oluhlaza, ubhontshisi wezinso, i-kale, i-kale, isipinashi. I-lutein ekhona emifino eluhlaza nasezithelo ezifana ne-ulethisi imahhala.
I-Lutein esithelweni nemifino ephuzi noma esawolintshi ikhona ngendlela yama-fatty acid esters e-lutein njenge-myristic acid, i-lauric acid, i-palmitic acid, njll., njengakumango, i-papaya, i-peach, iplamu (plum), ithanga, u-squash wasebusika, amawolintshi, njll., kunenqwaba ye-lutein esters, kunokuba i-lutein ester.
Ukuhlaziywa kwe-Spectroscopic kwathola ukuthi iningi lezakhi ze-pigment ezimbalini ze-marigold zikhona ngendlela yama-esters, akhiwa ikakhulukazi ama-lutein esters angama-8 ahlukene amafutha. Indlela yama-fatty acids nayo yenza i-lutein izinze ku-marigold.
4. Inqubo ye-Metabolic
I-Lutein ne-lutein esters isetshenziswa njengezinto ezingavuthiwe zokuvikela amehlo. Ukuthi umphumela muhle noma cha kuhlobene nokutholakala kwawo kanye nemetabolism. I-Lutein ngokwemvelo ikhona endaweni ye-macular yeso lomuntu kanye nobuchopho. Ucwaningo lwanamuhla luphinde lwathola ukuthi i-lutein ingamuncwa ngokuqondile futhi isetshenziswe ngumzimba ngokusebenzisa amathumbu omuntu.
I-Lutein ester ine-terminal fat fat structure, futhi i-molecule inkulu futhi ayikwazi ukusetshenziswa ngokuqondile. Idinga ukubola bese iguqulwa ibe yi-lutein yamahhala bese imuncwa futhi isetshenziswe.
I-bioavailability ye-lutein esters ihlobene nenani lamafutha ekudleni. I-Lutein esters ivamise ukudinga i-esterase noma i-lipase ukuze yenze i-hydrolysis, ngakho ukudla okusesilinganisweni kwamafutha kuyazuzisa ukumuncwa kanye nokusetshenziswa kwe-lutein esters.
5. Ukusebenza kahle
Yimuphi umphumela wokunakekela iso ongcono phakathi kwe-lutein ne-lutein ester ngethamo elifanayo? Eqinisweni, lolu daba alukapheli, kodwa singakwazi ukubona umehluko ekusebenzeni kahle kusukela ekubhaliseni ukudla kwezempilo.
Kusukela ngoJanuwari 2000 kuya kuFebhruwari 2022, uZhitiqiao wathatha ukudla kwezempilo okubhaliswe kuleli okungu-161 ukuze kuqede ukukhathala okubukwayo eminyakeni engama-22 edlule, okungama-73 kukho asebenzisa i-lutein kwathi abangu-4 basebenzisa i-lutein esters.
Ngaphezu kwalokho, phakathi kwemikhiqizo ebhalisiwe ye-lutein, imisebenzi yokunakekelwa kwezempilo engu-7-ibheke endaweni elwa{2}}ne-oxidation, futhi imikhiqizo emi-4 kuthiwa inomthelela wokuthuthukisa ukungatheleleki. Lokhu kungase kubonise ukuthi ukusebenza kahle kwe-lutein ekudleni kwezempilo kokunakekelwa kwamehlo kungaqashelwa kakhulu.
