2. Agenda 1. Standards 2. Macromolecules Notes 3. HW: Macromolecules Booklet Warm-Up Question What do you know about carbohydrates, lipids and proteins?

3. The Chemistry of Life

4. Which atoms are found in all living things? CHNOPS C = carbon H = hydrogen N = nitrogen O = oxygen P = phosphorus S = sulfur

5. Carbon (C) The atom that is the basis of all life. In organic chemistry, carbon atoms bond to each other to form chains, branches, and rings. Common substances made of C: - Diamonds - Coal - Graphite (pencil lead)

6. Molecules many molecules -> macromolecules macro = large molecule = atoms that hook up many atoms -> molecules

7. Macromolecules (Organic Compounds) Macromolecules are made of small units called monomers. mono = one A monomer is like one link in a chain. Many monomers put together make a polymer. poly = many A polymer is like a long chain with many links.

8. 4 types of polymers or macromolecules or organic compounds: Carbohydrates (sugar) Lipids (fat) Protein Nucleic Acids

9. Carbohydrates Monomer: monosaccharide (one sugar) Examples: glucose and fructose Examples: glycogen (stored energy), starch (potatoes), table sugar (sucrose), cellulose ( used in the cell wall of plants) Polymer: polysaccharide (many sugars) Glucose C 6 H 12 O 6

10. Lipids Monomers: fatty acid chains linked by a glycerol Polymer: Lipids Phospholipid Examples: Used in cell membranes, fat for insulation, waxes, oil, steroids (send messages), butter, and it stores energy

11. Proteins Monomers: amino acid Polymer: proteins (amino acids joined by peptide bonds) Examples: enzymes (chemical processes), cell structures, muscle contractions, meat, beans, nuts

12. Nucleic Acids Monomer: nucleotide (phosphate, sugar, nitrogen base) Polymer: nucleic acids Examples: DNA and RNA (store cell information, assist in making proteins)

13. What macromolecule applies to this picture? A. Carbohydrate B. Lipid C. Protein D. Nucleic Acid

14. Now you will create a book on these macromolecules… Title Page with your name 4 pages should have 1. Title 2. 3 sentences in your own words describing the macromolecule. 3. Pictures of one unit. 4. Pictures of items that contain these macromolecules.

15. In class finish first 2 pages Tonight - finish next 2 pages. Tomorrow - finish last 2 pages. Due at the next grading period.
