2. Introduction to Macromolecules
Biology I

3. Macromolecules
Macromolecules – molecules made of hundreds to thousands of smaller molecules that are linked together.

4. Macromolecule Examples

5. Who Cares?! Medical Casts Construction Rope Cushion in Mattresses
Polyester

6. Macromolecules Made by polymerization.
Single Monomer
Macromolecules
Polymer
Made by polymerization.
Large compounds are built by joining smaller compounds together, like putting together links on a chain.
A single compound is called a monomer; many individual compounds put together are called a polymer.
The monomers can be the same throughout the entire polymer, or they can be different.

7. Macromolecules How do you make a polymer?
Dehydration Synthesis – a chemical reaction that joins monomers together
This works by removing one water molecule for every pair of monomers put together.
How organisms store energy!

8. Dehydration Synthesis
Think like an athlete who is dehydrated, they are lacking water! Just like dehydration synthesis.
Dehydration Synthesis

9. Macromolecules How do you break a polymer?
Hydrolysis – a chemical reaction that breaks polymers apart.
This works by adding one water molecule for every pair of monomers that is separated.
Used to produce energy.

10. Think hydrolysis like being hydrated, or having water.

11. Macromolecules There are four types of macromolecules: Carbohydrates
Lipids
Proteins
Nucleic Acids
