In I/GCSE Chemistry, we will learn about fats & oils.
Fats & Oils
Fats + oils have more than one ester link.
Fats/oils + oxygen --> lots of energy (stored) [can be used later].
Fatty acids are carboxylic acids with long hydrocarbons chains.
Fatty acids [carboxylic acids] + glycerol [alcohol] --> fats /oils
Un/saturated fats
Animal fats: saturated hydrocarbon chains which mainly contain single C – C bonds
- Refer to I/GCSE Chemistry, The molecule has as much hydrogen as it can take.
- The saturate molecules are straight and in a regular shape --> solid at room temp.
- It tastes quite bitter
Vegetable oils: unsaturated hydrocarbon chains with lots of C = C double bonds.
- When it comes to I/GCSE Chemistry, The double bond means that there are carbon atoms that don’t form four bonds with other atoms and thus they are highly reactive --> unsaturated.
- The double bond means that the molecule isn’t straight and it in a more irregular shape. It is difficult to pack it into an ordered pattern --> liquid at room temp.
You got it now!
