What stabilizes secondary structure IMFs between side chains

What stabilizes secondary structure?

IMF\'s between side chains,

disulfide bonds

salt bridges

hydrogen bonds

all of the above

Solution

Secondary struture of a protein is stabilised by intermolecular forces or IMFs between side chains of aminoacids they are the hydrogen bonds between amine and carboxyl groups of aminoacids.

where as disulphide bonds, salt bridges and hydrogen bonds are the ones responsible for the tertiary structure stabilization of proteins.
