Metabolite Identification
Common Name(S)-2,3-Epoxysqualene
Description(S)-2,3-Epoxysqualene, also known as 2,3-oxidosqualene or (S)-squalene-2,3-epoxide, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Thus, (S)-2,3-epoxysqualene is considered to be an isoprenoid lipid molecule. (S)-2,3-Epoxysqualene is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. (S)-2,3-Epoxysqualene is an intermediate in the biosynthesis of terpenoid. It is a substrate for squalene monooxygenase and lanosterol synthase.
