lanosterol, mammalian precursor for all steriod hormones cholesterol How a noncyclic alkene is converted to the steriod ring skeleton squalene squalene epoxide rearrangement, followed by 1,2-shifts, then elimination of an H+ and loss of CH 3 s


  1. lanosterol, mammalian precursor for all steriod hormones cholesterol

  2. How a noncyclic alkene is converted to the steriod ring skeleton squalene squalene epoxide

  3. rearrangement, followed by 1,2-shifts, then elimination of an H+ and loss of CH 3 s as CO 2 yields lanosterol
