1 Carbohydrates

2 Single sugars Glucose Fructose

3 Glucose is used in Respiration to give you energy

4 Double sugars (disaccharides) Maltose (2 glucose units)

5 Double sugars (disaccharides) Sucrose (glucose + fructose)

6 Sucrose is every day sugar

7 Sucrose comes from sugarcane or sugar beets

8 Sucrose production process

9 The effect of too much sugar: Obesity Hyperactivity Diabetes And …

10 Starch is found in: Rice Bread Pasta Potatoes Corn

11 Starch is probably the most eaten molecule in the world

12 Starch is a chain of several Glucose molecules

13 Glucose is the building block for starch, cellulose and glycogen

14 Glucose, Fructose and other small sugars are tested with Benedict’s solution.

15 Benedict’s solution Change from blue to red or yellow when Glucose or Fructose is present.

16 Starch is tested with Iodine Change from brown to purple/black when starch is present.

17 Thank you
