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

I-7-Dehydrocholesterol iyimpuphu emhlophe ekristalu, impuphu ephuzi ekhanyayo ekristalu, ehlukanisiwe futhi ekhishwe esikhumbeni sengulube. Ingatholakala futhi ngokufaka i-esterification, i-bromination, i-exclusion, kanye ne-hydrolysis ye-cholesterol. Iphuzu lokuncibilika 150-151 ℃ (i-anhydrous). [α] 20/D-113.6 ° (chloroform). Ivezwa emoyeni ithambekele ekufakweni kwe-oxidation. I-medicament intermediate eyenziwe yi-saponification reaction ye-7-dehydrocholesterol. I-7-dehydrocholesterol (7-DHC) iyi-5,7-conjugated diene sterol kanye nesandulela se-cholesterol biosynthesis.

Isicelo

I-7-Dehydrocholesterol isetshenziswa kakhulu njengendawo ebalulekile yokwenziwa kwe-vitamin D3 kanye nesithasiselo ekunakekelweni kwesikhumba, ekuvikelweni kwelanga, nasezimonyweni. I-7-dehydrocholesterol (7-DHC) iyi-5,7-conjugated diene sterol kanye nesandulela se-cholesterol biosynthesis. Uma ivezwa emisebeni ye-ultraviolet B (UVB), inegalelo ekukhiqizweni kwe-vitamin D3. I-7-dehydrocholesterol iyindinganiso yangaphakathi yokunqunywa kwama-sterol futhi isetshenziswa njengezinye izinto zokwenza izinto zelebhu.
