1. Chapter 17 Naturally 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 3 1
