Key Stage 3
Meaning
Lipids are molecules found in fats and oils.
About Lipids
- Oil is better for us than fat, but we need some of both.
- If we eat too much fat and oil then we can become obese.
Meat contains useful fat for our diets, but too much can lead to heart disease. | Fish is a very healthy source of oils in our diet. | Nuts are a healthy source of oils. | Butter is full of fat and we shouldn't eat too much. Butter is found in cakes and cookies. | Cooking oil is used to fry our food causing it to have a lot of oil inside it. A small amount is healthy but too much is bad for us. |
Testing For Lipids
- Adding lipids to paper can turn the paper translucent.
Method
- 1. Take a small sample of food.
- 2. Wipe it on a piece of paper.
- 3. Hold the paper up to the light.
- 4. If the paper has turned translucent the food contained fat.
There are two patches where fat has been asborbed by the paper. |
