Question

Quizplus · Accepted Answer

Amino acid side chains with polar or charged structures dissolve best in water because water is a polar molecule and can interact with polar or charged groups through hydrogen bonding. Amino acid side chains that are non-polar cannot interact with water and therefore are more likely to be found in the hydrophobic interior of a protein or nonpolar solvent.
