Chapter 17Naturally Occurring Oxygen-Containing
Compounds

• Lipids
• Fats and Waxes (also called saponifiable lipids)
• the simplest lipids
• fats known as triglycerides
• waxes from long, straight-chain alcohols
• saponification (hydrolysis in NaOH to fatty acid
  salt and glycerol)
• micelles (soap-like hydrophobic and hydrophilic
  parts organize above a critical micelle
  concentration into a dynamic spherical
  structure)
• bilayer membranes (sandwich-like micelle of
  phospholipid with hydrophobic regions on inside
  and hydrophilic regions away surrounded by
  aqueous solution
• Terpenes (non-saponifiable lipids)
• comprised of isoprenoid sub-units, over 22,000
  known natural terpenes
• Steroids
• fused 6, 6 6, 5 rings
