Structure of Proteins - Secondary Structure
- Once the primary structure of the protein is formed, it begins to twist into regular patterns that make its secondary structure.
- These twists are formed as a result of the regular pattern of H-bonds.
- There are two types of secondary structures: α-helix and β-pleated sheets.
α-helix:
- It is a rod-like structure.
- Inner portion contains the backbone of the polypeptide and outer portion contains the side chains.
- The helical shape occurs because of the formation of H-bonds between the oxygen atom of the -CO group of one amino acid and the nitrogen atom of the -NH group of the fourth amino acid.
- Thus, the H-bonds are formed every fourth amino acid.
-
The H-bonds in alpha helix are formed every fourth amino acid.
