  1. Ch. 2 Review The Chemistry of Life

  2. 3. Lipids • Lipids include the following: a) fats b) waxes c) sterols d) fat-soluble vitamins (such as vitamins A, D, E, and K) e) monoglycerides f) diglycerides g) triglycerides h) phospholipids i) etc.

  3. Fats • Insoluble in water. • Triglycerides = glycerol + fatty acids chains. • May be either solid (fats) or liquid (oils) at room temperature. • Exs. of edible animal fats = lard, fish oil, butter/ghee and whale blubber. • Exs. of edible plant fats = peanut, soy bean, sunflower, sesame, coconut and olive oils, and cocoa butter. • Vegetable shortening & margarine made from hydrogenating oils.

  4. Saturated VS Unsaturated Fats

  5. Phospholipids • Make up cell membranes (AKA phospholipidbilayers). • Made of hydrophobic tails (water “fearing”) and a hydrophilic head (water “loving”).
