How Do Amino Acids React to Water and Oil?
... When amino acids are joined together in proteins, only their side chains (also called radicals or residues) are left free to interact with each other and molecules of their surrounding medium (water or lipids). These side chains, therefore, have a strong influence on how the protein behaves in water ...
