Bis2a 03.0 introduction to macromolecules

Food provides the body with the nutrients it needs to survive. Many of these critical nutrients are biological macromolecules, or large molecules, necessary for life. These macromolecules (polymers) are built from different combinations of smaller organic molecules (monomers). What specific types of biological macromolecules do living things require? How are these molecules formed? What functions do they serve? In this chapter, these questions will be explored.

Specifically we will address the four classes of macromolecules that compose all living cells: Proteins , Carbohydrates , Lipids , and nucleic acids .
