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

I-7-Dehydrocholesterol iyimpushana ecwebezelayo emhlophe, impushana ecwebezelayo ephuzi, ehlukanisiwe futhi ekhishwa esikhumbeni sengulube. Ingatholwa futhi nge-esterification, bromination, ukuqedwa, kanye ne-hydrolysis ye-cholesterol. Iphuzu lokuncibilika 150-151 ℃ (anhydrous). [α] 20/D-113.6 ° (chloroform). Ukuchayeka emoyeni kuthambekele ekubeni ne-oxidation. Umuthi ophakathi nendawo owenziwe 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 njengesithako esibalulekile sokuhlanganiswa kwevithamini D3 nanjengesengezo ekunakekeleni isikhumba, ukuvikela ilanga, nezimonyo. I-7-dehydrocholesterol (7-DHC) iyi-5,7-conjugated diene sterol kanye nesandulela se-cholesterol biosynthesis. Uma kuvezwe emisebeni ye-ultraviolet B (UVB), inomthelela ekukhiqizeni uvithamini D3. I-7-dehydrocholesterol iyindinganiso yangaphakathi yokunqunywa kwe-sterol futhi ibuye isetshenziswe njengamanye ama-reagents aselabhorethri.
