Metabolite Identification
Common Name24,25-Dihydrolanosterol
Description24,25-Dihydrolanosterol, also known as lanostenol, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Thus, 24,25-dihydrolanosterol is considered to be a sterol lipid molecule. 24,25-Dihydrolanosterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
