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.

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.
