Kodi all-trans-Retinol CAS 68-26-8 ndi chiyani?

Trans Retinol yonse ndi mtundu wa kristalo womwe umazimiririka wokhala ndi malo osungunuka a 62-64 ℃ ndi malo otentha a 120-125 ℃ (0.667Pa). Zosavuta kusungunuka mumafuta kapena organic solvents, osasungunuka m'madzi. Kukhazikika kwamafuta abwino, okhazikika pansi pamikhalidwe yamchere, osakhazikika pansi pa acidic. Mukakumana ndi antimony trichloride, imawonetsa mawonekedwe a buluu ndipo imawonongeka mosavuta ndi cheza cha ultraviolet ndi oxygen mumlengalenga. Ikhoza kutetezedwa mukakhala ndi vitamini C.

Kugwiritsa ntchito

Onse trans Retinol vitamini A ndi chigawo chimodzi cha zinthu photosensitive m'maselo zithunzi, amene angatsimikizire kukhulupirika ndi thanzi la epithelial minofu kapangidwe ndi kulimbikitsa chitukuko ndi kukula kwa thupi. Zikapanda, zimatha kulepheretsa kukula ndi chitukuko, kuchepetsa ntchito ya uchembere, ndikupangitsa "khungu lausiku" mosavuta. Trans Retinol yonse imagwiritsidwa ntchito m'mapiritsi amankhwala ndi makapisozi ngati chowonjezera cha vitamini pamakampani opanga chakudya.
