Protein Structure

• What bonds are in the tertiary structure of a protein?

  • Hydrogen Bonds
  • Ionic Bonds
  • Disulphide Bridge's
  • Hydrophobic + hydrophilic interactions
• The Secondary structure can become an Alpha Helix or a Beta-pleated sheet.
• The four levels of protein structure are:

  • Primary
  • Secondary
  • Tertiary
  • Quaternary
• The Hydrogen Bonds may form within the amino acid chains , pulling it into an alpha helix
• Polypeptide chains can also lie parallel to one another and can join by hydrogen bonds forming sheet like structures called beta-pleated sheets
• The structure of an amino acid is :

  • The Amine Group
  • Carboxylic acid group
  • variable group
• The formation of a peptide bond is a condensation reaction between the amine group of one amino acid and carboxylic acid group of another’s forming a water molecule.
