1.5 Lipids

• Lipids include fats (which are solid at room temperature) and oils (which are liquid at room temperature). These are called triglycerides.
• Fats are made from saturated fatty acids, meaning there are no carbon double bonds.

  Oils are made of unsaturated fatty acids, meaning they have carbon double bonds.
• TRIGLYCERIDE STRUCTURE:

  3 fatty acids & glycerol.

  Each fatty acid forms an ester bond with glycerol in a condensation reaction. The opposite of this is hydrolysis.
• TRIGLYCERIDE STRUCTURE:

  3 fatty acids & glycerol.

  Each fatty acid forms an ester bond with glycerol in a condensation reaction. The opposite of this is hydrolysis.
• Glycerol is an alcohol 🍸 with 3 carbon atoms and 3 hydroxyl groups (-OH).

  A fatty acid is a long hydrocarbon chain with a carboxyl group at one end (-COOH).
• 1 = fatty acid

  2 = glycerol

  
• Properties of Triglycerides:

  • Energy storage (due to large ration of energy storing carbon-hydrogen bonds) compared to the no. Carbon atoms. A lot of energy is stores in the molecule.
