FooDB Name | delta7-Avenasterol |
---|
Description | Constituent of oats and pumpkin seeds
delta7-Avenasterol is an intermediate in the biosynthesis of steroids (KEGG ID C15782). It is the 4th to last step in the synthesis of Stigmasterol and is converted from 24-Ethylidenelophenol. It is then converted to 5-dehydroavenasterol via the enzyme lathosterol oxidase [EC:1.14.21.6]. delta7-Avenasterol is found in many foods, some of which are robusta coffee, sunflower, oat, and common walnut. |
