LECTURE OBJECTIVES

AT THE END OF THIS LECTURE, YOU SHOULD BE ABLE TO:

1. Recognize the difference between inorganic and organic molecules, and understand the importance of four valence electrons in a carbon atom.
2. List the major functional groups found in organic molecules.
3. List and describe the structure and function of the four major groups of organic molecules.
4. List the major groups of molecules within each of the four major groups of organic molecules, and give examples of each.
5. Recognize the importance of structure in organic molecules (e.g., molecular formula vs. structural formulas, importance of functional groups, importance of hydrogen bonds, primary, secondary, tertiary, and quaternary structures of proteins, and helical structure of DNA)
6. Define selected key terms.
