Question

Discuss the four possible levels of protein structure and relate each level to particular bonding patterns.

Answer 1

The four levels of protein structures show five different bondings present in them such as hydrogen bonds, disulfide bonds, hydrophobic interactions, peptide bonds, and ionic bonds.

1. The primary structure of a protein is formed by linear linking of amino acids by peptide bonds
   
2. In proteins, the ionic bonds are formed between the ionized acidic or basic groups of amino acids.
3. Disulfide bond is a covalent bond formed from two this groups of two cysteine residues in a protein. It is found in the tertiary structure.
4. hydrogen bonds are involved in stabilizing secondary tertiary and quaternary structures of proteins
5. Hydrophobic interactions are found in beta-pleated structures such as in valine.
