I-Vitamin A iyivithamini encibilikayo ngamafutha

I-Vitamin A Palmitate iwuketshezi oluphuzi kuya kuwolintshi olusebenza njengekhemikhali eluhlaza. Ine-molecular formula ye-C36H60O2 kanye nesisindo se-molecular 524.87 g/mol. Lesi sakhi asincibiliki emanzini kodwa sincibilika kuzincibilikisi ezihlukahlukene eziphilayo. Ngokuhlanzeka okungu-≥ 98%, yaziwa ngokuzinza nempilo ende yeshelufu ngokuvamile eyiminyaka engu-2-3 uma igcinwe endaweni epholile, neyomile. I-Vitamin A Palmitate ayinaphunga futhi inephuzu lokuncibilika lika-28-29 °C. Isetshenziswa kakhulu ezimbonini ezahlukahlukene ngokuqukethwe kwayo kwe-vitamin A ephezulu, okungaba yinzuzo ezinhlelweni ezifana nezithasiselo, ukudla okuqinisiwe, nezimonyo.

    Isingeniso

    I-Vitamin A Palmitate, igama lekhemikhali njenge-retinol acetate, ivithamini yokuqala etholakalayo. Kunezinhlobo ezimbili ze-Vitamin A: eyodwa i-retinol okuwuhlobo lokuqala lwe-VA, ikhona ezilwaneni kuphela; enye i-carotene. I-retinol ingahlanganiswa ne-β-carotene evela ezitshalweni. Ngaphakathi komzimba, ngaphansi kwe-catalysis ye-β-carotene-15 kanye ne-15'-double oxygenase, i-β-carotene iguqulwa ibe i-ratinal ebuyiselwa ku-retinol ngokusebenza kwe-ratinal reductase. Ngakho-ke i-β-carotene ibizwa nangokuthi i-vitamin precursor.

    Isicelo

    ---Izithako Zokudla Okunomsoco:Kusetshenziswe kabanzi ekwakhiweni kwezithako zokudla okunomsoco. Idlala indima ebalulekile ekusekeleni umbono, umsebenzi wokuzivikela komzimba, kanye nesikhumba esinempilo.
    ---Ukudla Okuqinisiwe:Yengezwa kaningi emikhiqizweni yokudla ehlukahlukene ukuze uthuthukise ukondleka kwayo. Izibonelo ezivamile zihlanganisa ubisi oluqinile, okusanhlamvu, kanye namafomula ezingane.
    ---Izimonyo kanye Nokunakekelwa Kwesikhumba:I-Vitamin A, esesimweni se-retinol noma i-retinyl palmitate, iyisithako esidumile ezimonyoni nasemikhiqizo ye-skincare. Kwaziwa ngezinzuzo zayo ezingase zibe khona zokulwa nokuguga, njengokunciphisa ukubukeka kwemigqa emihle, imibimbi, nokukhuthaza ukushintshwa kwamaseli esikhumba.
    ---Amalungiselelo Ezemithi:Okuphuma ku-Vitamin A, okubizwa ngokuthi ama-retinoids, asetshenziswa ekwenziweni kwemithi. Zisetshenziswa ekwelapheni izimo zesikhumba ezahlukahlukene njenge-acne, psoriasis, ne-photoaging. Ama-retinoids angasiza ukulawula ukukhula kwamangqamuzana futhi akhuthaze impilo yesikhumba.
    ---Izithasiselo zokuphakela kwezilwane:Kufakwe ekwenziweni kokudla kwezilwane ukuze kuqinisekiswe ukukhula okufanele, ukukhula, kanye nempilo iyonke yemfuyo nezinkukhu. Kuyabasiza ukuba nomthelela ekusebenzeni kokuzala kanye nokusebenza komzimba wokuzivikela.
    ---Izithako Zempilo Yamehlo:Ivamise ukufakwa ezithasiselweni zezempilo zamehlo, kungaba njenge-retinol noma ngendlela ye-beta-carotene. Lezi zithako zihlose ukusekela impilo yamehlo iyonke futhi zingaba yinzuzo kubantu abasengozini yokuwohloka kwe-macular okuhlobene neminyaka (AMD) nezinye izimo zamehlo.
