| Common Name | Brassicasterol |
|---|
| Description | Brassicasterol belongs to the class of organic compounds known as ergosterols and derivatives. These are steroids containing ergosta-5,7,22-trien-3beta-ol or a derivative thereof, which is based on the 3beta-hydroxylated ergostane skeleton. Thus, brassicasterol is considered to be a sterol lipid molecule. Brassicasterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Brassicasterol is a potential CSF biomarker for Alzheimer’s disease (PMID: 21585343 ). |
