Yintoni i-all-trans-Retinol CAS 68-26-8?

I-All trans Retinol yikristale ye-flake efiphalayo enombala eneqondo lokunyibilika elingama-62-64 ℃ kunye neqondo lokubila elingama-120-125 ℃ (0.667Pa). Kulula ukuyinyibilikisa kwioyile okanye kwi-organic solvents, ayinyibiliki emanzini. Uzinzo oluhle lobushushu, izinzile phantsi kweemeko ze-alkaline, ayizinzile phantsi kweemeko ze-asidi. Xa idibana ne-antimony trichloride, ibonisa impendulo eluhlaza okwesibhakabhaka kwaye yonakaliswa lula yimitha ye-ultraviolet kunye ne-oxygen emoyeni. Ingakhuseleka xa ikunye ne-vitamin C.

Isicelo

Zonke iivithamini ze-trans retinol A ziyinxalenye yezinto ezibangela ukukhanya kwiiseli ezibonakalayo, ezinokuqinisekisa ukuthembeka kunye nempilo yesakhiwo sezicubu ze-epithelial kwaye zikhuthaze uphuhliso kunye nokukhula komzimba. Xa zingekho, zinokuthintela ukukhula kunye nophuhliso, zinciphise umsebenzi wokuzala, kwaye zikhokelele ngokulula "kwi-night blind". Zonke iivithamini ze-trans retinol zisetyenziswa kwiipilisi zamayeza kunye neekhaphu njengesongezelelo sokondla esisekelwe kwiivithamini kwishishini lokondla.
