Question

The helical structure of proteins is stabilised by

• A. hydrogen bonds
• B. glycosidic bonds
• C. all of these
• D. dipeptide bonds

Answer 1

The correct option is A hydrogen bonds

Hydrogen bonds

The weak bonds that are formed between hydrogen atom, already covalently bonded to another electronegative atom in a molecule, to another electronegative atom of another molecule are known as hydrogen bonds.

The $\alpha$ -helix or the helical structure of proteins is the secondary structure of a protein that is stabilised by the hydrogen bonds.
