Solution: Explain the process of protein folding, include the role of chaperone proteins.

Problem

Explain the process of protein folding, include the role of chaperone proteins.


Solution

There are four stages of protein folding; primary, secondary, tertiary and quaternary.

  • The primary structure is the sequence of amino acids held together by peptide bonds. In this process, amino acids begin to form a long, linear chain of protein.
  • The secondary structure is the protein beginning to fold up. It can have two types of structure:
    •  the alpha helix, a coil shape held by hydrogen bonds in the same direction as the coil. 
    • The beta pleated sheet is an S shape pattern, also with hydrogen bonds holding the structure together.
