1. Macro-molecules
“The Stuff of Life”

2. Macromolecules Macro = Large
Molecule = A group of atoms, held together by chemical bonds, in a specific structure.

3. Macromolecules
Polymers = macromolecules composed of sub-units called monomers.
Monomers- Smaller molecules able to make bonds with other molecules to form polymers.

4. Carbohydrates Sugars Starches- Structural- Store Energy
Cellulose- Plants
Chitin- Fungi, Insects

5. Carbohydrates Monomers = saccharide, or monosaccharide
Polymers = polysaccharide

6. Lipids
Fats
Oils
Waxes

7. Lipids
Store Energy
Structural- Cell Membrane

8. Lipids
Monomer = Fatty Acids
Saturated
Unsaturated

9. Proteins Provide Support Help with Chemical Reactions
Transport Substances
Hormones

10. Proteins Monomers = Amino Acids There are 20 Amino Acids
Proteins are chains of Amino Acids folded into complex shapes.
A protein’s function is related to it’s complex shape →

11. Nucleic Acids
DNA = Deoxyribonucleic Acid
RNA = Ribonucleic Acid

12. Nucleic Acids DNA- A double stranded molecule
RNA- A single stranded molecule

13. Nucleic Acids
DNA and RNA work together to store and transmit the genetic code.
DNA’s structure allows it to be copied.

14. Nucleic Acids Monomers = Nucleotides
Nitrogenous Bases- There are 4. Sequence determines genetic code.
Adenine- (A)
Thymine- (T)
Guanine- (G)
Cytosine- (C)
