Start-up for 9/15/16 You are going to watch a video introducing macromolecules. Complete a summary during the video answering the following two questions: 1) How do we obtain all of the molecules necessary for our body that we deplete throughout the day? 2) What are the 3 molecules we need what they made of and what are their job/s? Organic Chemistry Chapter 2 Sections 1 and 3 Carbon Compounds and Macromolecules Objectives: Students will A) B) C) D) E) F) G) H) I) Define 6 words related to macromolecules. Compare the 2 main types of bonds. Analyze why carbon is special. Summarize how monomers, polymers, and macromolecules are related. List the 4 classes of macromolecules Identify the function and building blocks of each macromolecule Analyze a day of personal diet explain whether or not it is healthy. Create a meal plan that incorporates all of the macromolecules. A) Define 6 words related to macromolecules. Units of Matter ….. What is the smallest thing of which everything is made? • • Atoms – basic unit of matter • Elements • C, O, H, N, S • Compounds & Molecules • CO2, H20, C6H1206 Check For Understanding • How are a proton, a neutron, and an electron similar and how are they different? A) Define 6 words related to macromolecules. • Proton – Nucleus, + charge Neutron • Nucleus, No charge Electron • Orbits, - charge Understanding Check Given the following clues, identify which word it represents. 1. Positive subatomic particle 2. Carbon 3. H2O 4. NaCl 5. Nucleus, no charge 6. Basic unit of matter 7. Orbit, negative charge 1. Proton 2. Element 3. Molecule 4. Compound 5. Neutron 6. Atom 7. Electron Start-up for September 16, 2016 1. Analyze the back of your food label. Under calories you will find three of the four macromolecule categories. What do you think they are? 2. List at least three things that are happening inside your body now. 3. Why do you think it is important to have a balance of macromolecules in your diet? 4. Why do you think obesity is such a problem in the U.S? Refer to the macromolecules in your answer B) Compare the two types of chemical bonds Ionic Bonds • From Ions • Ions – atoms that gain or lose electrons when bonding • Metal + Non-metal Covalent BONDS • Share electrons • Stronger than ionic that donate or Gain electrons • 2 non-metals Understanding Check Which type of bond is it and why?. 1. MgCl2 2. C6H12O6 3. H2O 4. NaCl 5. NH3 6. HCl 7. KBr 1. Ionic 2. Covalent 3. Covalent 4. Ionic 5. Covalent 6. Covalent 7. Ionic C) Analyze why carbon is special. These are real carbon compounds. Identify at least 2 unique carbon traits Amino Acids Glucose Propane A) Identify the special characteristics of carbon • • • Organic Compounds Organic = Living Contain carbon. Carbon = 4 electrons in its outside energy level. Needs 8 to fill Can bond on all 4 sides – Covalently Forms Huge Chains electron • • • neutron proton B) Summarize how monomers, polymers, and macromolecules are related. Polymer = many Monomer = single unit monomers Examples Examples Macromolecules = giant molecules Polymers are macromolecules formed through polymerization C) List the 4 classes of macromolecules 1. Carbohydrates 3. Protein 2. Lipids 4. Nucleic Acids Exit Ticket 1. Rank these in order from smallest to largest in relationship to each other: Element, Compound/Molecule, Atom, Subatomic particles. 2. What are many monomers linked together called? 3. What process links monomers? 4. Why is carbon the main element found in macromolecules? 5. What are the four macromolecules?
