UNIT OVERVIEW

This unit introduces organic macromolecules—very large molecules made by joining many smaller molecules together. You will learn about synthetic polymers (plastics) and biological macromolecules (carbohydrates, proteins, and nucleic acids).

What you will learn:

• How addition polymers form from alkene monomers
• How condensation polymers like nylon and polyesters form
• The structure and properties of common plastics
• The social and environmental impact of polymer use
• How biological macromolecules sustain life
• How molecular structure determines macromolecular properties

Why this matters:

Polymers are everywhere. The plastic bottle holding your water, the polyester in your school shirt, the proteins in your muscles, and the DNA that makes you unique are all macromolecules. Understanding their chemistry helps you understand the modern world.
