Amino Acids (T)

• What should you be able to describe by the end of the video?

  Structure of an amino acid and how amino acids form polypeptides and proteins
• What is the significance of condensation polymers in relation to amino acids?

  • Formed when different monomers react
  • Amino acids can react to form condensation polymers
• What is the name of the amino acid shown in the video?

  Glycine
• What are the two different functional groups present in amino acids?

  Amine group and carboxylic acid group
• How do amino acids react to form a condensation polymer?

  They react to form a condensation polymer by releasing a molecule of water
• What happens when two glycine molecules react together?

  • They form a condensation polymer
  • A molecule of water is released
• What does the letter 'n' represent in the reaction of glycine molecules?

  Number of glycine molecules taking part in the reaction
• What is the difference between a polypeptide and a protein?

  • Polypeptide: polymer made from one type of amino acid
  • Protein: polymer made from different types of amino acids
• What are the two important functional groups that all amino acids have?

  Amine group and carboxylic acid group
• What occurs when different amino acids are combined into the same polymer chain?

  • They form a protein
  • The polymer is now called a protein
