Lipids

Lipids

diverse groups pf molecules that contain regions composed almost entirely of hydrogen and carbon
1. large chains of nonpolar hydrocarbons
  1. double bonds say that it's unsaturated fat
  2. absence of double bonds, no unsaturated fat
2. hydrophobic
3. water insoluble
oils, fats and waxes
1. built from
  1. carbon
  2. hydrogen
  3. carboxylic acid group
2. fatty acids
  1. chains of carbon and hydrogen with carboxylic acid group
  2. saturated
    1. contain as many hydrogen atoms as posible
      1. no double bonds
      2. solid at room temperature
  3. unsaturated
    1. fewer hydrogen
      1. double bonds
      2. liquid at room temperature
      3. trans fat: human made
3. oils and fats
  1. formed by dehydration synthesis linking three fatty acids to glycerol
  2. triglycerides
  3. energy-storage
  4. oils: seeds from plants
  5. fats: produced by animals
4. waxes
  1. humans and most animals are not able to break them down
phospholipids
1. form a bilayer
  1. outside is hydrophilic
  2. inside it's hydrophobic
steroids
