  2. Objectives SWBAT describe the importance of carbohydrates by examining their role in the human body and their location in the food guide pyramid. SAT Word: perennial (adj.) lasting for a long time, persistent; (n) a plant that lives for many years Drill: • What is the role of Vitamin D in the body? • Identify 4 types of organic compounds. • What is the difference between organic and inorganic molecules? NOTEBOOK CHECK: Show us your drills

  3. Key Vocabulary • Macromolecule- a very large molecule • Monomer- a molecule that can combine with other molecules to form polymers (subunits of macromolecules) • Polymer a larger molecule formed from repeating subunits (monomers)

  4. Notes Carbohydrates

  5. What is a Carbohydrate? • A macromolecule used to store and release energy (short term) • Sugar & Starch

  6. What are the Types of Carbohydrates? • Monosaccharides- one sugar • Disaccharides- two sugars • Polysaccharides- many sugars

  7. What are Common Carbohydrates? • Glucose • Sucrose • Fructose • Cellulose • Lactose Did you notice a pattern?

  8. What are Common Carbohydrates? • Glucose • Sucrose • Fructose • Cellulose • Lactose Did you notice a pattern?

  9. What Does –ose Indicate? • The suffix –ose indicates________________.

  10. What is Glucose? • The most common simple sugar (______________) • Used as a source of energy for living things.

  11. What is Starch? • A ______ _______(polysaccharide) • Used a source of energy for living things.

  12. Monosaccharides • Glucose • Fructose • Galactose

  13. Disaccharides • Glucose + Glucose = • Glucose + Fructose= • Glucose + Galactose=

  14. Polysaccharides • Starch • Cellulose • Glycogen

  15. How do you test for the presence of simple sugars? • To test for the presence of simple sugars… use Benedict’s Solution. • Add 5 drops of Benedict’s Solution and heat. • If solution changes to orange, then simple sugars are present. Be n ed i c t s

  16. How do you test for the presence of Starch? • To test for the presence of starch… use Lugol’s solution (IKI iodine) • Add 3 drops of Lugol’s solution • If a solutions changes to blue-black, then starch is present. L U G O L S

  17. Work on this worksheet using your notes
