1. Macromolecules

2. Carbon One of the most important elements found in living things
If something is “organic”, it is a “carbon-based” organism meaning many of it’s molecules contain carbon
This is NOT in the notes guide, but you should write it down

3. What are Macromolecules?
Macromolecules are the large molecules that are necessary for life
These macromolecules include:
Carbohydrates
Lipids
Nucleic Acids
Proteins

4. Describing Macromolecules
We describe macromolecules by identifying their monomers and polymers
Monomers = single units
Polymers = many monomers bound together
Monomers are polymerized (joined together) to form a polymer

5. Describing Macromolecules

6. Carbohydrates Monomer: Monosaccharides (simple sugar)
Polymer: Polysaccharides (chain of sugars)
Function: Main source of energy & provides structure for some organisms
Example: Sugar, pasta, fiber, and starches

7. Lipids Monomer: Fatty Acids & Glycerol Polymer: Lipids
Function: Stores energy, part of cell membranes and waterproof coverings
Example: Oils, waxes and steroids

8. Nucleic Acids Monomer: Nucleotide Polymer: Nucleic Acids
Function: Carries genetic information
Example: Deoxyribonucleic Acid & Ribonucleic Acid

9. Proteins Monomer: Amino Acids Polymer: Proteins
Function: Builds bones and muscles, enzymes control rates of reactions, transport things in/out of cells, & helps fight disease
Example: Meat, Lactase, Cell Membrane Channels, White & Red Blood Cells
