The secondary structure of a protein refers to

Options

  1. A-helical backbone
  2. Bhydrophobic interactions
  3. Csequence of -amino acids
  4. Dfixed configuration of the polypeptide backbone

Correct answer

A. -helical backbone

Step-by-step solution

Secondary structure of proteins involves -helical back bond and -sheet structures. These structures are formed as a result of H -bonding between different peptide groups. Hence, (A) is correct
