Question

Define the following terms as related to proteins.
(i) Peptide linkage
(ii) Primary structure
(iii) Denaturation

Answer 1

(i) Peptide Linkage: A peptide bond is an amide type of covalent chemical bond sinking two consecutive alpha-amino acids from $C$ of one alpha-amino acid and $N_2$ of another along a peptide chain as shown in the diagram.

(ii) Primary Structure: The sequence of amino acids describe the primary structure of the protein.

(iii) Denaturation: Destroying the structure and activity of a protein by some actions like boiling is called Denaturation.

An example is Boiling of eggs.
