ukunyibilika | Zonke ii-retinol esters azinakunyibilika emanzini, zinyibilika okanye zinyibilika ngokuyinxenye kwi-ethanol ene-anhydrous kwaye ziyaxutywa kunye nezinyibilikisi eziphilayo.I-Vitamin A kunye neester zayo zivakalelwa kakhulu kwisenzo somoya, i-oxidising agents, i-acids, ukukhanya kunye nobushushu.Yenza uvavanyo kunye nazo zonke iimvavanyo ngokukhawuleza kangangoko kunokwenzeka, ugweme ukuvezwa kukukhanya kwe-actinic kunye nomoya, i-oxidising agents, i-oxidation catalysts (umz. ubhedu, isinyithi), i-acids kunye nobushushu;sebenzisa izisombululo ezisanda kulungiswa. |
IVithamin A inokusebenza njenge-keratinization regulator, inceda ekuphuculeni ukumila kolusu, ukuqina, kunye nokuguda.I-Vitamin A esters, kanye esikhumbeni, iguqulela kwi-asidi ye-retinoic kwaye ibonelele ngeenzuzo zokuchasana nokuguga.I-Vitamin A ikholelwa ukuba ibalulekile kwisizukulwana kunye nokusebenza kweeseli zesikhumba.Ukunqongophala kwevithamin A eqhubekayo kubonisa ukuwohloka kwezicubu zedermal, kwaye ulusu luba lukhuni kwaye lome.Ukusetyenziswa komphezulu wevithamin A kunceda ukuthintela ukomisa kolusu kunye nokuqina, ukugcina ulusu lusempilweni, lucacile, kwaye luxhathisa usulelo.Iimpawu zayo zokuvuselela ulusu zibonakala ziphuculwe xa zidityaniswe ne-vitamin E.IVithamin A yeyona nto iphambili kwiioyile ezifana nesibindi secod kunye nokrebe, kunye neentlanzi ezininzi kunye neoyile yemifuno.Bona kwakhona iretinol;i-retinoic acid;retinylpalmitate.
