1. Describe the primary function of the four types of macromolecules
Describe the basic molecular structure of the four types of macromolecules.
Describe the primary function of the four types of macromolecules

2. MACROmolecules
Objective: Compare and contrast the basic molecular structures and primary functions of the four categories of macromolecules
Essential Question: How do different macromolecules meet our needs?
can the four different macromolecules be distinguished or recognized

3. Why is Carbon so unique? Each carbon atom is identical
Carbon can bond with other carbon atoms
carbon bonds with hydrogen, nitrogen, oxygen, sulfur and phosphorus
form long chains or rings.

4. Most COMMON ELEMENTS in LIVING ORGANISMS
All macromolecules are made up of a CARBON BASE.
CARBON
HYDROGEN EC
NITROGEN
Most COMMON ELEMENTS in LIVING ORGANISMS
OXYGEN
PHOSPHOROUS
SULFUR
CHNOPS

5. Macromolecules of life
Carbohydrates
Lipids
Proteins
Nucleic acids
MACROmolecules are POLYMERS
All four macromolecules are in living things. They are found in our food because our food comes form living things!! We need food to survive!

6. What is your favorite food?
What does it do for your body? Let’s find out!

7. Think-pair-share! What do the prefixes “macro” and “micro” mean?
What do the prefixes “poly” and “mono” mean?

8. Mono = one, Poly = many, “mer”=molecule
MONOMER is a small molecule that is a individual subunit in a much larger molecule
POLYMERS are LARGE MOLECULES made of many monomers bonded together.
POLYMERIZATION
POLYMERS
MONOMERS

9. Macromolecules of Life: Carbohydrates
Elements:
Carbon, Hydrogen, Oxygen
Structure:
Rings, 2 hydrogen to 1 carbon
Functions:
Short-term energy storage
Provide fast energy
Structural support in cell wall of plants

10. Macromolecules of Life: Carbohydrates
Monomers are…
Monosaccharides: simple sugars (glucose)
Polymers are…
Polysaccharides: complex sugars formed when simple sugars bond to form larger carbohydrates
Include starches, cellulose, glycogen

11. What do you notice? SUGAR!!!!!! Various types: Lactose Fructose
Glucose
Galactose
What do you notice?

13. Carbohydrates provide immediate energy
Carbohydrates provide immediate energy. Example: running races or playing sports

14. Examples of Carbohydrates
Bread
Potatoes
Corn
Beans
Rice
Pasta

15. Macromolecules of Life: Proteins
Elements:
Carbon, Hydrogen, Oxygen, Nitrogen & sometimes sulfur (R Group)
Structure
- Form chains (N-C-C)
Function: Shape determines the function
Control reaction rates (enzymes)
Regulate cell processes
Transport across C.M.
Form and move bones/muscles

16. Macromolecules of Life: Proteins
Monomer: Amino acids
20 different amino acids combine to make proteins
Proteins differ in number and order of amino acids
Polymer: Polypeptide chain

17. Why do we need proteins? Muscles, ligaments, tendons, and bones
Without these particular structural proteins, we would look more like this….

19. Examples of Proteins
A-mean-o acids

20. Macromolecules of Life: Nucleic Acid
Elements:
Composed of: Carbon, Hydrogen, Oxygen Nitrogen, Phosphorus
Structure:
Helix (double or single)
Function:
Store and transmit genetic info
Build protein

21. What washes up on beaches?
Nucleic Acid
Monomers: nucleotides
Made of a sugar, phosphate group, and nitrogen base
Polymers:
What washes up on beaches?
Nucleotides
DNA (stores genetic information.)
RNA (builds proteins)

22. Macromolecules of Life: Lipids
Elements:
- carbon, hydrogen, and oxygen
Structure:
Chains made of Glycerol and three (3) fatty acids

23. Macromolecules of Life: Lipids
Function:
Provide long-term energy storage/ waterproof covering
Phospholipids are main component of cell membrane
Used to make hormones

24. Examples of Lipids
Examples: FATS, OILS, WAXES, STEROIDS (cholesterol)

25. Connecting Claudel What organelle builds Claudel’s proteins?
What macromolecule composes Claudel’s cell membrane?
Where does Claudel get the instructions to build proteins? What macromolecule is that?
If Claudel is preparing to run a race, which
macromolecule does Claudel want to consume?
