The Making of Macromolecules Objective: To understand that basic molecular structure and primary function of the four categories of macromolecules. Materials: molecular model kit, dichotomous key, textbook Procedure: 1. Using the molecular model kit you will build a model of one of the four monomers. A B C D E 2. Use the dichotomous key to determine which monomer you have built. Does it have a ring structure in its main chain? Yes No Does it have a nitrogen in its main chain No Fatty Acid Is there a phosphate group attached? Yes Amino Acid Yes Nucleic Acid No Sugar 3. Now that you’ve identified what type of monomer you’ve built, determine which polymer it produces. 4. Create a foldable that includes the following information: The name of the macromolecule The polymer The structure An example The monomer Its function Analysis: 1. How are these four macromolecules similar? 2. What elements do these 4 different macromolecules seem to have in common? 3. What is the relationship between a monomer and a polymer?
