Kodi 7-Dehydrocholesterol CAS 434-16-2 ndi chiyani?

7-Dehydrocholesterol ndi ufa wa crystalline woyera, ufa wonyezimira wachikasu wonyezimira, wodzipatula komanso wotengedwa pakhungu la nkhumba. Itha kupezekanso ndi esterification, bromination, kuchotsa, ndi hydrolysis ya cholesterol. Malo osungunuka 150-151 ℃ (anhydrous). [α] 20/D-113.6 ° (chloroform). Kuwonetsedwa ndi mpweya kumakhala kosavuta kutulutsa okosijeni. Mankhwala apakati opangidwa ndi saponification reaction ya 7-dehydrocholesterol. 7-dehydrocholesterol (7-DHC) ndi 5,7-conjugated diene sterol ndi kalambulabwalo wa cholesterol biosynthesis.

Kugwiritsa ntchito

7-Dehydrocholesterol imagwiritsidwa ntchito ngati gawo lapakati lofunikira pakuphatikizika kwa vitamini D3 komanso ngati chowonjezera pakusamalira khungu, kuteteza dzuwa, ndi zodzoladzola. 7-dehydrocholesterol (7-DHC) ndi 5,7-conjugated diene sterol ndi kalambulabwalo wa cholesterol biosynthesis. Akakumana ndi cheza cha ultraviolet B (UVB), amathandizira kupanga vitamini D3. 7-dehydrocholesterol ndi muyezo wamkati wodziwitsa ma sterols komanso amagwiritsidwa ntchito ngati ma reagents ena a labotale.
