| Common Name | 5-Dehydroavenasterol |
|---|
| Description | 5-Dehydroavenasterol 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, 5-dehydroavenasterol is considered to be a sterol lipid molecule. 5-Dehydroavenasterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 5-Dehydroavenasterol is an intermediate in the biosynthesis of steroids. 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 1.14.21.6). It is then converted into Isofucosterol via the enzyme 7-dehydrocholesterol reductase (EC 1.3.1.21). |
