Ionic bonding and hydrogen bonding are the two stronger interactions between amino acids. They contribute to the stability and structure of proteins.

The two stronger interactions between amino acids are ionic bonding and hydrogen bonding.

Ionic bonding: Ionic bonds result from electrostatic attractions between positively and negatively charged side chains of amino acids. For example, the mutual attraction between an aspartic acid carboxylate ion and a lysine ammonium ion helps maintain the folding of proteins.
Hydrogen bonding: Hydrogen bonding forms between a highly electronegative oxygen atom or a nitrogen atom and a hydrogen atom attached to another oxygen atom or a nitrogen atom in polar amino acid side chains. Hydrogen bonding plays a crucial role in both intra- and intermolecular interactions of proteins.

These two interactions contribute to the stability and structure of proteins.
