| ukuncibilika | Wonke ama-retinol ester awancibiliki emanzini, ayancibilika noma ancibilike ngokwengxenye ku-ethanol engadonsi amanzi futhi axubane nezinyibilikisi eziphilayo.I-Vitamin A nama-esters ayo azwela kakhulu esenzweni somoya, ama-oxidizing agents, ama-acids, ukukhanya nokushisa.Yenza ukuhlolwa kanye nazo zonke izivivinyo ngokushesha ngangokunokwenzeka, ugweme ukuchayeka ekukhanyeni kwe-actinic nomoya, ama-oxidizing agents, ama-oxidation catalysts (isb. ithusi, insimbi), ama-asidi nokushisa;sebenzisa izixazululo ezisanda kulungiswa. |
I-Vitamin A ingasebenza njengesilawuli se-keratinization, esiza ukuthuthukisa ukuthungwa kwesikhumba, ukuqina, nokushelela.I-Vitamin A esters, uma isesikhunjeni, iguqulela ku-retinoic acid futhi inikeze izinzuzo zokulwa nokuguga.I-Vitamin A kukholakala ukuthi ibalulekile ekukhiqizeni nasekusebenzeni kwamangqamuzana esikhumba.Ukushoda kwe-vitamin A okuqhubekayo kubonisa ukuwohloka kwezicubu zesikhumba, futhi isikhumba siba sikhulu futhi some.Ukufakwa kukavithamini A ebusweni kusiza ekuvimbeleni ukomisa kwesikhumba kanye nokuqina, kugcina isikhumba sinempilo, sicacile, futhi simelana nezifo.Izici zayo zokuvuselela isikhumba zibonakala zithuthukisiwe uma zihlanganiswa novithamini E.I-Vitamin A iyingxenye enkulu yamafutha anjenge-cod isibindi noshaka, namafutha amaningi ezinhlanzi namafutha emifino.Bheka futhi isihloko esithi retinol;i-retinoic acid;i-retinylpalmitate.
