| Common Name | delta7-Avenasterol |
|---|
| Description | delta7-Avenasterol, also known as 7-dehydroavenasterol or 24Z-ethylidenelathosterol, 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, delta7-avenasterol is considered to be a sterol lipid molecule. delta7-Avenasterol has been detected, but not quantified in, several different foods, such as garden onions, fenugreeks, vaccinium (blueberry, cranberry, huckleberry), grapefruit/pummelo hybrids, and pulses. This could make delta7-avenasterol a potential biomarker for the consumption of these foods. delta7-Avenasterol is an intermediate in the biosynthesis of steroids. It is the fourth to last step in the synthesis of stigmasterol and is converted from 24-ethylidenelophenol. It is then converted into 5-dehydroavenasterol via the enzyme lathosterol oxidase (EC 1.14.21.6). |
