1. When finished…  Draw and label the structure for carbohydrates, lipids, nucleic acids, and amino acids.  How many amino acids are there?  What are the four parts of an amino acid?  What is nucleic acid used for?  What are lipids used for?  What are carbohydrates used for?  USE YOUR BOOK AND CHROME BOOK!

2. Proteins  Subunits are amino acids  Made up of C, H, O, N, and sometimes S FunctionExample Structure/supportcollagen Fight infection antibodies (immune system) Transport hemoglobin carries O 2 Catalystenzyme Movement actin & myosin in muscle

3. Amino Acids  Consists of…  Central carbon (brown)  Amino group (blue)  Carboxyl group (orange)  Hydrogen atom (white)  R group (green) 20 different R groups form 20 different amino acids

4. Linking Amino Acids  Condensation reaction/dehydration synthesis links amino group of one amino acid with carboxyl group of next  Forms a peptide bond between amino acids Water forms as a by-product

5. Bonding in Proteins  2 amino acids  dipeptide  More than 2 amino acids  polypeptide  DNA determines the sequence of amino acids in a protein or polypeptide chain.  Sequence of amino acids is unique to each protein

6. Amino Acid/Protein Video  Write down 3 facts on a sheet of paper  https://www.youtube.com/watch?v=qB RFIMcxZNM

7. Protein Lab  DEFINITELY want your GOGGLES for this one!  Clean up after yourself  If it gets on your hands wash immediately.

8. Flipbook  Answer questions first.  Cut out parts from nucleic acid page and glue a protein on the back side.

9. Monday Closure  How do we test for proteins?  What do proteins do for our bodies?  What is the ratio of carbohydrates?  What does STERNGRR stand for?
