7-Dehydrocholesterol CAS 434-16-2
He paura tioata mā te 7-Dehydrocholesterol, he paura tioata kōwhai mārama, i wehea, i tangohia mai i te kiri poaka. Ka taea hoki te whiwhi mā te esterification, te bromination, te whakakorenga, me te hydrolysis o te cholesterol. Ko te ira rewa 150-151 ℃ (anhydrous). [α] 20/D-113.6 ° (chloroform). Ka ngāwari te waikura mēnā ka pāngia e te hau. He takawaenga rongoā i hangaia mā te tauhohenga saponification o te 7-dehydrocholesterol. Ko te 7-dehydrocholesterol (7-DHC) he 5,7-conjugated diene sterol me te precursor mō te biosynthesis cholesterol.
