Chii chinonzi 7-Dehydrocholesterol CAS 434-16-2?

7-Dehydrocholesterol ichena crystalline poda, yakareruka yeyero crystalline poda, yakaparadzaniswa uye yakabviswa paganda renguruve. Inogona zvakare kuwanikwa ne esterification, bromination, kubviswa, uye hydrolysis yecholesterol. Melting point 150-151 ℃ (anhydrous). [α] 20/D-113.6 ° (chloroform). Inoratidzwa kumhepo inowanzoitika kune oxidation. Mushonga wepakati wemishonga wakagadzirwa ne saponification reaction ye 7-dehydrocholesterol. 7-dehydrocholesterol (7-DHC) inonzi 5,7-conjugated diene sterol uye inotangira cholesterol biosynthesis.
