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

Yonke i-trans Retinol iyikristalu ye-flake efiphalayo enombala enephuzu lokuncibilika elingu-62-64 ℃ kanye nephoyinti elibilayo elingu-120-125 ℃ (0.667Pa). Kulula ukuncibilika emafutheni noma kuma-organic solvents, angancibiliki emanzini. Ukuzinza okuhle kokushisa, kuzinzile ngaphansi kwezimo ze-alkaline, azinzile ngaphansi kwezimo ezine-asidi. Lapho ihlangana ne-antimony trichloride, ibonisa ukusabela okuluhlaza okwesibhakabhaka futhi ilinyazwa kalula imisebe ye-ultraviolet nomoya-mpilo osemoyeni. Ingavikeleka uma ihlangene novithamini C.

Isicelo

Wonke ama-trans Retinol vitamin A ayingxenye yezinto ezithatha izithombe kumaseli abonakalayo, angaqinisekisa ubuqotho nempilo yesakhiwo sezicubu ze-epithelial futhi akhuthaze ukukhula nokukhula komzimba. Uma ingekho, ingavimbela ukukhula nokuthuthuka, yehlise umsebenzi wokuzala, futhi iholele kalula "ekungaboni ebusuku". Yonke i-trans Retinol isetshenziswa kumaphilisi emithi namaphilisi njengesengezo sokuphakelayo esisekelwe kuvithamini embonini yokudla.
