Unit Objectives

Basic Chemistry Review- Make sure you feel comfortable with the review concepts (see sheet provided)
Be able to identify the 4 major biomolecules and their properties: Lipids, Carbohydrates, Nucleic acids, and proteins

For each of the four biomolecules above, you should be able to list or draw:
The general structure
The name of the single or monomeric unit
The name of the polymers formed.
Important uses of this type of molecule in the body.

Explain how polymers are made through dehydration synthesis and broken down through hydrolysis.
Explain the importance of water to life, including cohesion, adhesion and its role as a solvent.
Chemical indicators are used to Identify macromolecules
