What are the four structural levels of a protein |
Primary structure Secondary structure Tertiary structure Quaternary structure |
|
What is the primary structure |
Sequence of amino acids in the polypeptide chain |
|
What is the secondary structure |
The hydrogen bonds which form between amino acids in the chain, these make it COIL into an alpha helix or beta pleated sheet |
|
What is the tertiary structure |
Bonds form between different parts of the chain - hydrogen and ionic, this forms the proteins final 3d structure |
|
What is Quaternary structure |
Some proteins are made if several polypeptide chains, for these proteins the quaternary structure is the final 3d structure |
|
Examples of proteins |
Enzymes Antibodies Transport proteins Structural proteins |
