Common Name(1r,3as,3bs,7s,9ar,9bs,11ar)-9a,11a-dimethyl-1-[(2r,3e)-6-methylhept-3-en-2-yl]-1h,2h,3h,3ah,3bh,4h,6h,7h,8h,9h,9bh,10h,11h-cyclopenta[a]phenanthren-7-ol
Description22-Dehydrocholesterol belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 22-dehydrocholesterol is considered to be a sterol. (1r,3as,3bs,7s,9ar,9bs,11ar)-9a,11a-dimethyl-1-[(2r,3e)-6-methylhept-3-en-2-yl]-1h,2h,3h,3ah,3bh,4h,6h,7h,8h,9h,9bh,10h,11h-cyclopenta[a]phenanthren-7-ol is found in Amphilectus fucorum, Axinella cannabina, Bugula neritina, Cliona celata, Crambe crambe, Cystoseira elegans, Dictyopteris delicatula, Dragmacidon lunaecharta, Dysidea fragilis, Echinometra lucunter, Encope emarginata, Ulva linza, Eutreptia viridis, Haliclona oculata, Halocynthia aurantium, Hydrodictyon reticulatum, Hypnea japonica, Kalanchoe petitiana, Neofibularia nolitangere, Nostoc carneum, Obelia longissima, Padina gymnospora, Palythoa caribaeorum, Petrosia ficiformis, Petrosia weinbergi, Phallusia nigra, Phyllidiella pustulosa, Posidonia oceanica, Prorocentrum balticum, Pyrocystis lunula and Salpa thompsoni.
