Metabolite Identification
Common Name25-Methylgramisterol
Description25-Methylgramisterol 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. 25-Methylgramisterol is an extremely weak basic (essentially neutral) compound (based on its pKa).
