Ivithamin A yivithamin enyibilikayo ngamafutha

IVithamin A Palmitate lulwelo olutyheli ukuya kuorenji olusebenza njengemathiriyeli ekrwada yeekhemikhali. Inayo i-molecular formula ye-C36H60O2 kunye ne-molecular weight of 524.87 g / mol. Le khompawundi ayinyibiliki emanzini kodwa inyibilika kwiintlobo ngeentlobo zezinyibilikisi eziphilayo. Ngokucoceka kwe-≥ 98%, iyaziwa ngokuzinza kwayo kunye nobomi obude beshelufu yesiqhelo yeminyaka eyi-2-3 xa igcinwe kwindawo epholileyo, eyomileyo. IVithamin A Palmitate ayinavumba kwaye inendawo yokunyibilika eyi 28-29 °C. Isetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo kumxholo wayo we-vitamin A ephezulu, enokuba luncedo kwizicelo ezifana nezongezelelo, ukutya okuqinisiweyo, kunye nezithambiso.

Intshayelelo

IVithamin A Palmitate, igama lekhemikhali njenge-retinol acetate, yeyona vitamin yokuqala yafunyanwa. Kukho iintlobo ezimbini zeVithamini A: enye i-retinol yindlela yokuqala ye-VA, ikhona kuphela kwizilwanyana; enye i-carotene. IRetinol inokudityaniswa yi β-carotene evela kwizityalo. Ngaphakathi komzimba, phantsi kwe-catalysis ye-β-carotene-15 kunye ne-15'-double oxygenase, i-β-carotene iguqulwa ibe yi-ratinal ebuyiselwa kwi-retinol ngokusebenza kwe-ratinal reductase. Ngaloo ndlela i-β-carotene ikwabizwa ngokuba yi-vitamin precursor.

Isicelo

---Izongezo zezondlo:Zisetyenziswe ngokubanzi kuqulunqo lwezongezo zesondlo. Idlala indima ebalulekileyo ekuxhaseni umbono, ukusebenza kwamajoni omzimba, kunye nolusu olusempilweni.

---Ukutya okongeziweyo:Zisoloko zongezwa kwiintlobo ngeentlobo zeemveliso zokutya ukunyusa ixabiso lezondlo zazo. Imizekelo eqhelekileyo ibandakanya ubisi oluqinisiweyo, iisiriyeli, kunye nomxube weentsana.

---Izithambiso kunye noKhathalelo loLusu:I-Vitamin A, ngendlela ye-retinol okanye i-retinyl palmitate, isithako esidumileyo kwiimveliso zokuthambisa kunye ne-skincare. Iyaziwa ngeenzuzo zayo zokuchasana nokuguga, ezifana nokunciphisa ukubonakala kwemigca emihle, imibimbi, kunye nokukhuthaza ukuguqulwa kweeseli zesikhumba.

---Amalungiselelo oNyango:Izinto eziphuma kwi-Vitamin A, ezaziwa ngokuba zii-retinoids, zisetyenziswa kumalungiselelo amayeza. Zisetyenziselwa ukunyanga iimeko ezahlukeneyo zolusu ezifana ne-acne, i-psoriasis, kunye ne-photoaging. I-Retinoids inokunceda ukulawula ukukhula kweeseli kunye nokukhuthaza impilo yesikhumba.

---Izongezo zesondlo sezilwanyana:Ukufakwa kwimixube yokutya kwezilwanyana ukuqinisekisa ukukhula okufanelekileyo, ukukhula, kunye nempilo yonke yemfuyo kunye neenkukhu. Ibancedisa ekusebenzeni kokuzala kunye nokusebenza komzimba.

---Izongezo zeMpilo yaMahlo:Yiba rhoqo kwizongezo zempilo yamehlo, nokuba yi-retinol okanye ikwimo ye-beta-carotene. Ezi zongezelelo zijolise ekuxhaseni impilo yamehlo ngokubanzi kwaye inokuba luncedo kubantu abasengozini ye-macular degeneration (AMD) enxulumene nobudala kunye nezinye iimeko zamehlo.
