  1. CH2OH O H H H OH H OH HO H OH Carbohydrates: _________________

  2. sugar sugar sugar sugar sugar sugar sugar sugar Carbohydrates • Building block molecules = ____________ sugar - sugar - sugar - sugar - sugar

  3. sucrose Carbohydrates • Function: • ________________ • ________________ • ________________ • cell wall in plants • Examples • ________________ • ________________ • ________________ glucoseC6H12O6 starch

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

  5. Building carbohydrates • Synthesis 1 sugar = monosaccharide 2 sugars = disaccharide | glucose | glucose | maltose mono = one saccharide = sugar di = two

  6. Building carbohydrates • Synthesis 2 sugars = disaccharide 1 sugar = monosaccharides | sucrose (table sugar) | glucose | fructose How sweetit is!

  7. BIG carbohydrates • __________________________ • __________________________ • _________________ • energy storage in plants • ________________ • _________________ • energy storage in animals • ________________ • _________________ • structure in plants • ________________ • _________________ • structure in arthropods & fungi • ________________ poly = many

  8. Building BIG carbohydrates _______________ glucose + glucose + glucose… = __________ (plant) energystorage __________ (animal)

  9. enzyme enzyme Digesting starch vs. cellulose starcheasy todigest cellulosehard todigest

  10. Cellulose • Cell walls in plants • ___________________________________ • most ______________________________ • that’s why they __________________to get their energy & nutrients • __________________ • stays undigested • keeps material moving in your intestines

  11. Different Diets of Herbivores Cow ___________ cellulose well; no need to eat other sugars Gorilla ___________ cellulose well; must add another sugar source, like fruit to diet

  12. Helpful bacteria • How can cows digest cellulose? • bacteria live in their stomachs & help digest cellulose-rich (grass) meals Eeeew…Chewingcud?

  13. Let’s build some Carbohydrates!
