What is Isofucosterol?

Plain description, key identifiers and synonyms

Isofucosterol is a 3beta-sterol consisting of stigmastan-3beta-ol with double bonds at positions 5 and 24(28). The double bond at postion 24(28) adopts a Z-configuration. It has a role as an animal metabolite, a marine metabolite, a plant metabolite and an algal metabolite. It is a 3beta-hydroxy-Delta(5)-steroid, a C29-steroid, a member of phytosterols and a 3beta-sterol. It derives from a hydride of a stigmastane.
