Bonds present in alpha helix are:

Correct answer: A. Hydrogen bonds

  • A. Hydrogen bonds
  • B. Ionic bonds
  • C. Disulphide linkage
  • D. Peptide bonds

Explanation

The bonds present in an alpha helix are hydrogen bonds. In an alpha helix, the backbone of the polypeptide chain forms a helical structure stabilized by hydrogen bonds between the carbonyl oxygen atom of one amino acid and the amide hydrogen atom of another amino acid. These hydrogen bonds occur between the carbonyl group (C=O) of the nth amino acid and the amide group (N-H) of the (n+4)th amino acid along the chain, creating a stable and regular helical conformation.

About Biological Molecules

The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
