Description: Lanosterol is a triterpene that derives from the chair-boat-chair-boat folding of 2,3-oxidosqualene. It is metabolized to CHOLESTEROL and CUCURBITACINS. Lanosterol is a naturally-occurring sterol and biosynthetic precursor of several animal, fungal, and protozoan steroids, including cholesterol and ergosterol. Defects in the processing of lanosterol contribute to a wide variety of disorders, including the formation of cataracts. Similarly, certain fungicides act by blocking lanosterol processing by fungi.
