Structure of the Molecules
Differences between Oils and Fats
- Fats are solids at room temperature while oils are liquids at room temperature.
- The melting points of fats are higher than the melting points of oils.
Saturated and Unsaturated Fats
- Saturated fats molecules are molecules where the fatty acids contain single carbon-carbon
(– C – C –) covalent bonds.
- Unsaturated fat molecules are molecules where the fatty acids that contain single (– C – C –) and double ( – C = C – ) covalent bonds between carbon atoms in their hydrocarbon chain.
- Unsaturated fats can be converted to saturated fats when react with hydrogen gas at temperature 180° in the presence of nickel as catalyst.
- The reaction is an addition reaction.
- This process is used in manufacturing margarine.
- Table below summarise the difference between saturated fat and unsaturated fat.
