Metabolite Identification
Common Name 5-Dehydroavenasterol
Description 5-Dehydroavenasterol is an intermediate in the biosynthesis of steroids (KEGG ID C15783). It is the third to last step in the synthesis of Stigmasterol and is converted from delta 7-Avenasterol via the enzyme lathosterol oxidase [EC:]. It is then converted to Isofucosterol via the enzyme 7-dehydrocholesterol reductase [EC:].
