Metabolite Identification
Common Name24-Methylenelophenol
Description24-Methylenelophenol, also known as 4.alpha-methylepisterol or gramisterin, 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, 24-methylenelophenol is considered to be a sterol lipid molecule. 24-Methylenelophenol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
