CHAPTER 4 and 5
ORGANIC CHEMISTRY AND MACROMOLECULES
1. “Organic chemistry” is the study of which specific atom?
Below is a diagram of a “carbon atom”.
2. How many valence electrons (outer energy level) does carbon have?
3. What two properties make carbon so important to chemistry?
Below is a diagram of “polymerization”.
4. What is the difference between a “monomer” and a “polymer”
(look at the prefix)?
5. What do the black lines connecting the monomers in the polymer
structure represent?
6. What are two other names that can be interchanged with
“polymer”?
Below is a chart containing the 4 organic “macromolecules”.
7. What 3 atoms are found in all 4 macromolecules?
8. Which macromolecules contain nitrogen?
9. Which macromolecule contains phosphate?
10. Which macromolecules would be found in you?
Below are diagrams of different “monosaccharides” in both linear and ring forms.
11. What do you notice about each monosaccharide
name?
12. What is the chemical formula for glucose
(C_H_O_)?
13. What are the macromolecules of carbohydrates
called?
Below is a diagram of a triglyceride molecule.
14. What type of macromolecule does a
triglyceride belong to?
15. What does the “tri” reference in this
molecular structure?
15. What are the 3 common categories of this
type of macromolecule?
16. Are these “saturated” or “unsaturated”
fatty acids?
Below is a diagram of a “nucleotide”.
18. On the diagram, label the 3 parts of a nucleotide?
17. What is the name of the polymer that is composed of this
monomer?
Below is a diagram of the monomer that forms a protein.
18. What is the name of this monomer?
19. How many different amino acids are found in nature?
20. What makes each amino acid different?
