cholesta-8,24-dien-3-ol, 4,4,14-trimethyl-, (3b,5a)-
a triterpene that derives from the chair-boat-chair-boat folding of 2,3-oxidosqualene. it is metabolized to cholesterol and cucurbitacins. Constit. of wool fat used e.g. as chewing-gum softener. Also from yeast Lanosterol is a tetracyclic triterpenoid, which is the compound from which all steroids are derived. (Wikipedia)
