AP Biology / Unit 1: Chemistry of Life
1.3 Introduction to Macromolecules
Notes
Macromolecules are polymers built from monomers.
- Dehydration synthesis: joins monomers, removes water.
- Hydrolysis: breaks polymers, adds water.
| Polymer | Monomer |
|---|---|
| carbohydrate | monosaccharide |
| protein | amino acid |
| nucleic acid | nucleotide |
Practice
Joining two amino acids releases:
Dehydration synthesis.
Digesting starch into glucose is an example of:
Water is added to break bonds.
The monomer of a nucleic acid is a:
Sugar, phosphate and base.
