Common Name(1r,3as,3bs,5r,5ar,7s,9ar,9bs,11ar)-1-[(2r,5r)-5-ethyl-6-methylheptan-2-yl]-9a,11a-dimethyl-tetradecahydrocyclopenta[a]phenanthrene-5,5a,7-triol
DescriptionStigmastane-3beta,5alpha,6beta-triol, also known as 5alpha,6beta-dihydroxysitosterol or sitostanetriol, belongs to the class of organic compounds known as stigmastanes and derivatives. These are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. Thus, stigmastane-3beta,5alpha,6beta-triol is considered to be a sterol. (1r,3as,3bs,5r,5ar,7s,9ar,9bs,11ar)-1-[(2r,5r)-5-ethyl-6-methylheptan-2-yl]-9a,11a-dimethyl-tetradecahydrocyclopenta[a]phenanthrene-5,5a,7-triol is found in Apis mellifera, Breynia fruticosa and Machilus zuihoensis. (1r,3as,3bs,5r,5ar,7s,9ar,9bs,11ar)-1-[(2r,5r)-5-ethyl-6-methylheptan-2-yl]-9a,11a-dimethyl-tetradecahydrocyclopenta[a]phenanthrene-5,5a,7-triol was first documented in 2003 (PMID: 12898426). Based on a literature review very few articles have been published on stigmastane-3beta,5alpha,6beta-triol.
