    The secondary structure of a protein refers to       AIEEE  Solved  Paper-2007

    A)  \[t=0,\]helical backbone

    B)         hydrophobic interactions

    C)         sequence of a-amino acids

    D)         fixed configuration of the polypeptide backbone

    Correct Answer: A

    Solution :

    Primary structure involves sequence of \[{{C}_{p}}-{{C}_{y}}=28R\]amino acids polypeptide chain. Secondary structure involves \[{{I}_{1}}\]helical backbone\[{{I}_{2}}\]pleated sheet like structures. These structures are formed as a result of H-bonding between different peptide groups.
