- 1Define denaturationThe destruction of the secondary, tertiary and quaternary structure.
- 2How does heat denature proteins?It breaks weak bonds.
- 3How does pH denature proteins?It changes ionisation patterns of side chain groups.
- 4How does reducing agents denature proteins?It reduces 'S double bond S' to SH.
- 5How does organic solvents denature proteins?It disturbs hydrophobic and hydrophilic interactions.
- 6How does detergents denature proteins?It disrupts the hydrophobic interactions.
- 7Primary structureLinear chain of amino acids.
- 8Secondary structureRegions stabilised by hydrogen bonds between atoms of the polypeptide backbone.
- 9Tertiary structure3-D shape stabilised by interactions between side chains of amino acids.
- 10Quaternary structureAssociation of two or more polypeptides (two or more tertiary structures).
- 11Define chaperoninsThey assist with the folding of proteins correctly and properly.
