  1. Carbohydrates Name______________

  2. sugar sugar sugar sugar sugar sugar sugar sugar Carbohydrates • Building block molecules = • Made of only Carbon, Hydrogn, Oxygen sugars sugar - sugar - sugar - sugar - sugar

  3. sucrose Carbohydrates • Function: • quick energy • energy storage • structure • cell wall in plants • Examples • sugars • starches • cellulose (cell wall) glucoseC6H12O6 starch

  4. CH2OH O H H H OH H OH HO H OH glucose sucrose fructose C6H12O6 Sugars = building blocks -ose • Names for sugars usually end in • glucose • fructose • sucrose • maltose

  5. Building carbohydrates • Dehydration Synthesis simple sugar = monosaccharide double sugar = disaccharide | glucose | glucose | maltose mono = one saccharide = sugar di = two

  6. Building carbohydrates • Dehydration Synthesis simple sugar = monosaccharide double sugar = disaccharide | sucrose (table sugar) | glucose | fructose How sweetit is!

  7. BIG carbohydrates-polysaccharides • starch • energy storage in plants • potatoes • glycogen • energy storage in animals • in liver & muscles • cellulose • structure in plants • cell walls • chitin • structure in arthropods & fungi • exoskeleton poly = many

  8. Building BIG carbohydrates polysaccharide glucose + glucose + glucose… = starch (plant) -roots -fruits energystorage glycogen (animal) -liver cells -muscle cells

  9. Cellulose • Cell walls in plants • herbivores can digest cellulose well • most carnivores cannot digest cellulose • that’s why they eat meatto get their energy & nutrients • cellulose = fiber • stays undigested • keeps material moving in your intestines

  10. Polysaccharides

  11. Digesting Carbohydrates = Hydrolysis!

  12. Helpful bacteria • How can cows and termites digest cellulose so well whereas humans CANNOT? • BACTERIA live in their stomachs & help digest cellulose-rich (grass) meals Eeeew…Chewingcud?
