The helical structure of protein is stabilized by:
The helical structure of protein is stabilized by:
dipeptide bonds
hydrogen bonds
ether bonds
peptide bonds
Solution
The helical structure of proteins or the alpha helix is the secondary structure of proteins and it is stabilized by hydrogen bonds. In helical structure, the carbonyl oxygen atoms in $\mathrm{C}=$ $\mathrm{O}$ points in one direction, towards the amide hydrogen atoms in $\mathrm{N}-\mathrm{H}$ groups, 4 residues away.
