Inkcazo
Ifomula yemolekyuli yelutein nguC40H56O2, kunye nobunzima bemolekyuli obungama-568.85. Umgubo o-orenji omthubi, intlama okanye ulwelo, olunganyibilikiyo emanzini, lunyibilika kwizinyibilikisi zendalo ezifana nehexane. Yona ngokwayo i-antioxidant kwaye inokufunxa ukukhanya okuyingozi njengokukhanya okuluhlaza okwesibhakabhaka.
Imisebenzi ye lutein yile ilandelayo:
1. Ukuthintelwa kwezifo ezinxulumene nokutyeba
2. Ukuphucula umsebenzi obonakalayo kwizigulane ezine-macular degeneration (AMD) ehambelana neminyaka kunye nabantu abanempilo
3. Ukunciphisa umngcipheko wesifo senhliziyo kubantu abaphilileyo
4. Ukunciphisa umonakalo wesikhumba owenziwe yi-UV kubantu abaqhelekileyo
5. Ukufaka imibala kwizithungu zeqanda, inkukhu, kunye nokutya kwenkukhu
6. Umsebenzi wokulwa nomhlaza
Umsebenzi kunye neSicelo
I-Lutein yinto yendalo ekhoyo ngokubanzi kwimifuno, iintyatyambo, iziqhamo kunye nezinye izityalo. Ihlala kwizinto zentsapho ye "carotenoid". Okwangoku, kuyaziwa ukuba kukho iintlobo ezingaphezu kwama-600 ze-carotenoids kwindalo. Malunga neentlobo ezingama-20 zegazi lomntu kunye nezicubu. I-Carotenoids efunyenwe ebantwini iquka i-dα-carotene, i-P1 carotenoids, i-cryptoxanthin, i-lutein, i-lycopene, kwaye akukho nanye i-flavins. Uvavanyo lwezonyango lubonise ukuba i-lutein yendalo equlethwe kwizityalo yi-antioxidant egqwesileyo.I-Lutein ikhuselekile kakhulu, ayinayo ityhefu kwaye ayinabungozi. Ingongezwa ngokuthe ngqo ekutyeni okufana ne-vitamin, i-lysine kunye nezinye izongezo zokutya ezisetyenziswa ngokuqhelekileyo.
I-Xanthophyll yeyona nto ibalulekileyo kwi-retina yomntu. Kukho ukuxinana okuphezulu kwe-Xanthophyll kwi-macula (umbono ophakathi) kunye ne-lens ye-retina yamehlo. Umzimba womntu awukwazi ukwenza i-Xanthophyll ngokwayo, kwaye kufuneka ithathwe ekutyeni. Emva kokugqobhoza kubo bonke ubunzima, i-Xanthophyll ingena kwi-lens kunye ne-macular ukwenza iziphumo ze-antioxidant, kwaye yenza i-radicals yamahhala eyingozi, kwaye ihluze ukukhanya okuluhlaza okwesibhakabhaka (okuyingozi kwiliso), kwaye uthintele umonakalo we-oxidation emehlweni obangelwa ukukhanya kwelanga.
I-Xanthophyll yendalo yi-antioxidant egqwesileyo, enokuthintela ukuvela kweeseli kunye namalungu omzimba ukuguga xa yongezwa ekutyeni ngesixa esifanelekileyo. Isenokuthintela ukuwohloka kwamehlo kunye nokungaboni okubangelwa kukukhula kweretina macular degeneration, kwaye isenokusetyenziswa njengezongezo zokutya ukuze kungcoliswe inyama yenkukhu kunye namaqanda, kunye nombala kunye nezongezo zokutya kwishishini lokutya.
