Identify the noncovalent interaction that results in proteins folding into a globe-like shape, forming a 'water-loving' exterior. Give two examples of amino acids that will have this interaction.

Hydrophobic interaction. Examples of amino acids that can form this interaction are valine and phenylalanine.

Hydrophilic interaction. Examples of amino acids that can form this interaction are threonine and glutamine.

Ionic interaction. Examples of amino acids that can form this interaction are aspartic acid and arginine.

Hydrogen bonding. Examples of amino acids that can form this interaction are asparagine and serine.
