2. House Keeping When taking notes today you will have several Q! (questions) that you will write in your notes to help you study. You only need to write when there is a Q!. When studying for quizzes and tests… make sure that you are can answer all of these Q!’s.

3. “PROTEIN NOTES” 4 Organic Macromolecules Q! What are the 4 Organic Macromolecules? 1. Carbohydrates (notes last week) 2.Proteins (today) 3.Lipids 4.Nucleic Acids Help with Cornell Note Taking- Q! What does organic mean? Organic=the molecule contains carbon!

4. Extra Questions/Conversation/HSA Questions 1. Which of these supply the main energy source used in cellular respiration? A.lipids B.amino acids C.nucleic acids D.carbohydrates 2. A dog gets many nutrients from its food including amino acids. Which of these can be built directly using the amino acids? A.proteins B.carbohydrates C.lipids D.minerals

5. Objective: By the end of class you will be able to use the chemistry (the building blocks/functions) of macromolecules in order to explain the difference between carbohydrates and proteins. Your Exit Quiz will look like this: Exit Quiz: MacromoleculeBuilding BlockFunctionFood Example 1. Carbohydrate 2. Protein

6. Today’s Feature Proteins

7. Q! Where do we find proteins? MEAT! Chicken Beef Pork Fish Other sources! Nuts Beans Tofu DAIRY! Eggs Cheese Milk

8. Q! What is the Structure of Proteins? Building Block = Amino Acids Amino Acid

9. Structure of Proteins Building Block = Amino Acids

10. Repeating units to make long chains (polymers of amino acids) Amino Acid Q! What is the Structure of Proteins?

11. Q! What are complete vs. incomplete proteins? Complete Proteins have all the amino acids. MEAT! Animal sources of proteins have ALL amino acids: Chicken Beef Pork Fish Eggs Incomplete proteins have SOME of the amino acids: Grains (bread/rice/pasta etc) Vegetables Beans

12. How Proteins Fold

13. Functions of Proteins Proteins have 3 main functions

14. Q! What are the Functions of Proteins? 1.Control the rate of reactions –These proteins are called enzymes –Enzymes speed up chemical reactions in a cell

15. Functions of Proteins continued… 2.Form bone and muscle –Help with muscle movement –Provide support for tissues and hair

16. Functions of Proteins continued… 3.Transport substances in/out of cells –Form channels in the cell membrane –Only let certain things pass through

17. Protein Recap Try to fill these in on your own to prepare for your exit quiz! Organic molecules have ________. Building Blocks = Functions = 1. 2. 3.

18. Protein Recap Try to fill these in on your own to prepare for your exit quiz! Organic molecule Building Blocks = Amino Acids Functions = 1. Control the rate of reactions 2. Form bone and muscle 3. Transport substances

19. Prepare for you exit quiz! Study your notes on…. And Carbohydrates Proteins!

20. Objective: By the end of class you will be able to use the chemistry (the building blocks/functions) of macromolecules in order to explain the difference between carbohydrates and proteins. Exit Quiz: MacromoleculeBuilding BlockFunctionFood Example 1. Carbohydrate 2. Protein

21. Optional Protein Exit Quiz Write the answers only!! 1. Organic molecules have to contain______. 2. Building Blocks of protein are 3. 2 functions of proteins are 1. 2. 1. Control the rate of reactions 2. Form bone and muscle 3. Transport substances

22. Start Your “Macromolecule Menu!” For Starters… Begin an outline of foods that would go in the following categories: 1.Foods made from monosacharides 2.Foods made from disacharides 3.Foods that are complete proteins 4.Foods that incomplete proteins After learning about lipids you will be expected to complete your menu that will include all macromolecules!
