This chapter describes the four major classes of biological molecules: carbohydrates, lipids, proteins, and nucleic acids. You will learn about the molecular structures of these biological molecules, their similarities and differences, and the roles they play. The chapter begins with a discussion of photosynthesis and oxidation of glucose as processes that are responsible for the major transformations and movements of carbon. It concludes with a discussion of metabolic reactions that provide and use energy. Chapter Outline
