Yintoni i-7-Dehydrocholesterol CAS 434-16-2?

I-7-Dehydrocholesterol yipowder emhlophe ekristale, ipowder etyheli ekhanyayo, ekhutshiweyo kwaye ikhutshwe kwisikhumba sehagu. Ingafunyanwa nangokuyinyibilikisa, ukunyibilikisa i-bromination, ukukhupha, kunye nokuyinyibilikisa i-cholesterol. Inqanaba lokunyibilika yi-150-151 ℃ (i-anhydrous). [α] 20/D-113.6 ° (chloroform). Ivezwa emoyeni isengozini yokunyibilika. I-pharmaceutical intermediate eyenziwe yi-saponification reaction ye-7-dehydrocholesterol. I-7-dehydrocholesterol (7-DHC) yi-5,7-conjugated diene sterol kwaye ingumlandeli we-cholesterol biosynthesis.

Isicelo

I-7-Dehydrocholesterol isetyenziswa kakhulu njengesixhobo esibalulekileyo sokwenziwa kwevithamini D3 kwaye njengesongezelelo ekunyamekeleni ulusu, ukhuseleko elangeni, kunye nezinto zokuthambisa. I-7-dehydrocholesterol (7-DHC) yi-5,7-conjugated diene sterol kwaye ingumqalisi we-cholesterol biosynthesis. Xa ivezwa kwimitha ye-ultraviolet B (UVB), inegalelo ekuvelisweni kwevithamini D3. I-7-dehydrocholesterol ngumgangatho wangaphakathi wokumisela ii-sterol kwaye ikwasetyenziswa njengezinye izinto zelebhu.
