Topics:

5. Introduction to Protein Structure & Function
   • What are the main organic molecules in organisms?
   • How do structures of proteins account for their functions?
   • How do cells synthesize and break down proteins?
   1. Explain the roll of the proteins in organisms
      1. List and recognize the four components of an amino acid, and explain how amino acids may be grouped according to the physical and chemical properties of the side chains
      2. Explain how amino acids contribute to biological diversity
      3. Describe how and where peptide bonds are formed and broken in proteins using condensation and hydrolysis reactions
   2. Define four levels of protein structure
      1. Describe primary structure and describe how it may be deuced in the laboratory
      2. Define the two types of secondary structure, and explain the role of hydrogen bonds in maintaining the structure
      3. Explain how weak interactions and disulfide bridges contribute to tertiary protein
      4. Explain how quaternary structure is reached in a protein include examples like hemoglobin
   3. Describe how proteins are made and modified within a cell
   4. List the major groups of proteins and give examples of each.

Time Range:
7 days

Suggested Teaching Strategies:

• Students will read and take their own notes on the chapter (maybe in outline form)
• Lecture on nature amino acids structure and side chains, and how they contribute to diversity of life
• Lecture on how and where peptide bonds are formed
• Lecture on how DNA controls the synthesis of proteins
• Lecture on four levels of protein structures
• Students take notes on lecture (maybe in outline form)
• Students will fill out cross word puzzle that uses terms from the chapter
• Students will fill out chapter study guide to compliment their lecture and board notes
