•Fructose
Simple Carbohydrates
Glucose is used in Respiration to give you energy
Simple Carbohydrates
Double sugars (disaccharides)•Maltose (2 glucose units)
Simple Carbohydrates
Double sugars (disaccharides)•Sucrose (glucose + fructose)
Simple Carbohydrates•Sucrose is every day sugar
Simple Carbohydrates•Sucrose comes from sugarcane or sugar beets
Simple Carbohydrates
•Sucrose production process
Simple CarbohydratesThe effect of too much sugar:• Obesity• Hyperactivity• Diabetes• And …
Complex CarbohydratesStarch is found in:•Rice•Bread•Pasta•Potatoes•Corn
Complex CarbohydratesStarch is probably the most eaten molecule in the world
Complex CarbohydratesStarch is a chain of several Glucose molecules
Complex CarbohydratesGlucose is the building block for starch, cellulose and glycogen
Test for CarbohydratesGlucose, Fructose and other small sugars are tested with Benedict’s solution.
Test for CarbohydratesBenedict’s solution Change from blue to red or yellow when Glucose or Fructose is present.
Test for CarbohydratesStarch is tested with Iodine
Change from brown to purple/black when starch is present.
