1. Proteins Enzymes are Proteins

2. Proteins Proteins: a chain of amino acids 20 different amino acids are found in proteins

4. Amino Acid Structure

5. Amino Acid + Amino Acid Amino acids are linked together via covalent bonds (electrons are shared). Does this polymer have more or less energy than NaCl? Why?

6. Dehydration Synthesis H 2 O molecule is released When talking about proteins, it links together amino acids. aka peptide bond formation

7. Dehydration Synthesis

8. Linking Amino Acids

9. Dehydration Synthesis Practice

10. Protein Folding Charges on proteins interact Positively charged Negatively charged Polar Non- polar Which charges “like” each other? Which charges “dislike” each other?

12. Protein

13. Human Protein Chain Get excited
