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

I-trans Retinol yonke iyikristalu elifiphalayo elinombala elinendawo yokuncibilika engu-62-64 ℃ kanye nendawo yokubila engu-120-125 ℃ (0.667Pa). Kulula ukuncibilika ku-oyili noma ku-organic solvents, ayincibiliki emanzini. Ukuqina okuhle kokushisa, kuzinzile ngaphansi kwezimo ze-alkaline, akuzinzile ngaphansi kwezimo ze-acidic. Uma ihlangana ne-antimony trichloride, ibonisa ukusabela okuluhlaza okwesibhakabhaka okuhlukile futhi yonakaliswa kalula yimisebe ye-ultraviolet kanye nomoya-mpilo emoyeni. Ingavikelwa uma ihambisana ne-vitamin C.

Isicelo

Yonke i-trans Retinol vitamin A iyisici sezinto ezithinta ukukhanya emaseli abonakalayo, ezingaqinisekisa ubuqotho kanye nempilo yesakhiwo sezicubu ze-epithelial futhi zikhuthaze intuthuko nokukhula komzimba. Uma ingekho, ingaphazamisa ukukhula nokukhula, yehlise umsebenzi wokuzala, futhi iholele kalula "ekungabonini ebusuku". Yonke i-trans Retinol isetshenziswa kumaphilisi emithi kanye nama-capsule njengesithasiselo sokudla esisekelwe kumavithamini embonini yokudla.
