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

7-Dehydrocholesterol ipfu chena yekristaro, upfu hwekristaro hweyero yakapfava, hwakabviswa paganda renguruve uye hunobviswa. Hunogonawo kuwanikwa ne esterification, bromination, emission, uye hydrolysis ye cholesterol. Nzvimbo yekunyunguduka 150-151 ℃ (anhydrous). [α] 20/D-113.6 ° (chloroform). Inowanikwa mumhepo inokurumidza kuoxidation. Mishonga inogadzirwa ne saponification reaction ye 7-dehydrocholesterol. 7-dehydrocholesterol (7-DHC) i 5,7-conjugated diene sterol uye inotangira cholesterol biosynthesis.

Kushandiswa

7-Dehydrocholesterol inonyanya kushandiswa sechinhu chakakosha chekugadzira vhitamini D3 uye sechinhu chinowedzera mukuchengetedza ganda, kudzivirira zuva, uye zvizoro. 7-dehydrocholesterol (7-DHC) i5,7-conjugated diene sterol uye inotangira kugadzirwa kwecholesterol. Kana ikasangana nemwaranzi ye ultraviolet B (UVB), inobatsira mukugadzirwa kwevhitamini D3. 7-dehydrocholesterol chiyero chemukati chekuongorora ma sterol uye chinoshandiswawo semamwe ma reagents emurabhoritari.
