Chemical Information
FooDB Name5-Dehydroavenasterol
Description5-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:]. [HMDB]. 5-Dehydroavenasterol is found in many foods, some of which are daikon radish, nance, skunk currant, and jujube.
