A. Yini i-beta carotene?
Izaqathi ziqukethe Inani elikhulu le-beta-i-carotene, engaguqulwa ibe uvithamini A ngemva kokungenisa izitho zokugaya zomuntu. Njengamanje iwumkhiqizo ophephe kunayo yonke yokwengeza uvithamini A (umane nje ungezelele ngamakhemikhali okwenziwa uvithamini A, ukweqisa kuzokwenza abantu babe nobuthi). Igcina impilo yamehlo nesikhumba, ithuthukisa ubumpumputhe ebusuku, isikhumba esimahhadlahhadla futhi isiza ukuvikela umzimba kuma-radicals mahhala. Hhayi ngeviniga nezinye izinto ezine-acidic ngesikhathi esifanayo.
B. Iyini imiphumela kanye nemisebenzi ye-carotene?
1. Gcina ubuqotho besikhumba kanye nolwelwesi lwamafinyila, vimbela isikhumba esomile nesimahhadla;
2. akha izinto ezithatha izithombe emangqamuzaneni abonakalayo;
3. ukukhuthaza ukukhula nokuthuthukiswa, ukukhuthaza ngempumelelo impilo kanye nokuthuthukiswa kwamangqamuzana, ukuvimbela ukuntula kokuzalwa. Ikhuthaza ukukhula okunempilo kwamathambo namazinyo;
4. Gcina umsebenzi wokuzala;
5. Gcina futhi ukhuthaze umsebenzi wokuzivikela komzimba. I-carrot inomsebenzi wokuvimbela nokucindezela umdlavuza wamaphaphu. Lapho i-carotene equkethwe izaqathi ingena emzimbeni, iguqulwa ibe uvithamini A. I-molecule ngayinye yesanqante ingaguqulwa ibe ama-molecule amabili kavithamini A.
I-Carotene iyisithako esisebenza ngokusebenza komzimba esingaguqulwa sibe uvithamini A ezilwaneni futhi ingakwazi ukwelapha ubumpumputhe ebusuku, isifo samehlo esomile kanye ne-epithelial keratosis. Inganqanda ukusabela okweqile kwamangqamuzana avikela amasosha omzimba, icime ama-peroxides abangela ukuvinjelwa kwamasosha omzimba, igcine uketshezi lwe-membrane, isize ukugcina isimo se-membrane receptor esidingekayo ekusebenzeni kokuzivikela komzimba, futhi ibambe iqhaza ekukhululweni kwama-molecule avikelayo. Ngokusebenzisa indlela engenhla, umsebenzi wokunqanda-umsebenzi we-tumor wama-lymphocyte, ama-giant titsh cell kanye namaseli e-NK wathuthukiswa, ikakhulukazi umdlavuza wamaphaphu, umdlavuza womminzo, i-squamous cell carcinoma, njll., obe nomthelela omkhulu wokuvimbela nokuthuthukisa, ngakho unamandla okulwa{4}}nomdlavuza, {5}umdlavuza, i-anticancer{6} esetshenziswa{6} njengemithi{6} imboni yezemithi. Ngenxa yokumelana kwayo nama-radicals mahhala, inemiphumela yokwelapha ezifweni zenhliziyo nemithambo yegazi nezinye izifo ezingamahlalakhona.
C. Ingasetshenziswa kuphi i-BETA carotene?
Njengebala elincibilikayo likawoyela odliwayo, -i-carotene ngokwayo ingamboza yonke imibala ukusuka kobomvu kuye kophuzi ngenxa yomehluko wokugxilisa ingqondo, ngakho yamukelwe ngokufudumele yimboni yokudla. Ifaneleka kakhulu ukuthuthukiswa kwemikhiqizo yamafutha kanye nemikhiqizo yamaprotheni, njenge-pigment yewolintshi edliwayo kanye nesithuthukisi sokudla okunomsoco, njengemajarini, i-capsule, imikhiqizo yokuhlanza i-pulp yezinhlanzi, imikhiqizo yemifino, ama-noodle asheshayo, njalonjalo. I-Microencapsulated beta{3}}i-carotene ingashintshwa ibe amanzi{4}}i-soluble pigment, engasetshenziswa cishe kukho konke ukudla. Ngaphezu kwalokho, -i-carotene kokuphakelayo, izimonyo nezinye izici zinokusetshenziswa okubalulekile.
