Welcome to Module 2

Chapter 3 - The Molecules of the Cell.

In this chapter, you will review the macromolecules of the cell. This chapter covers organic molecules, proteins, carbohydrates, lipids, and nucleic acids.

You will read the chapter, complete the chapter 3 homework, a macromolecule lab, and a dynamic study module for the chapter. Helpful videos are in your E-text, assignments, and PowerPoints.

Please review the start and due dates for these chapters.

As always, should you have any questions, please do not hesitate to contact me.

Sincerely,

Dr. Burke

Module Learning Outcomes

Upon successful completion of this module, you will be able to:

Introduction to Organic Compounds

3.1 Explain why carbon is unparalleled in its ability to form large, diverse molecules.

3.1 Define organic compounds, hydrocarbons, a carbon skeleton, and an isomer.

3.2 Describe the properties of and distinguish between the six chemical groups important in the chemistry of life.

3.3 List the four main classes of macromolecules important to life. Explain the relationship between monomers and polymers. Compare the processes of dehydration synthesis and hydrolysis.

Carbohydrates

3.4–3.7 Describe the structures, functions, properties, and types of carbohydrate molecules common in the human diet.

3.6 Explain why the Food and Drug Administration (FDA) has proposed changes to the nutrition facts on packaged food labels to include grams of added sugars.

Lipids

3.8–3.11 Describe the structures, functions, properties, and types of lipid molecules.

3.9 Describe the scientific evidence that suggests that there is a greater health risk associated with the consumption of trans fats than saturated fats.

3.10 Describe the unique structural properties of phospholipids that make them essential for cell membranes.

3.11 Describe the health risks associated with the use of anabolic steroids.

Proteins

3.12–3.14 Describe the structures, functions, properties, and types of proteins.

3.13–3.14 Explain how a protein’s shape determines its functions.

3.14 Describe the four levels of structure of a protein.

Nucleic Acids

3.15 Compare the structures and functions of DNA and RNA, noting similarities and differences.

3.16 Describe the adaptive advantage of lactose tolerance in people of East African descent.
