Question

Quizplus · Accepted Answer

Side chains, also known as R groups, are important in determining the shape and solubility of proteins. The particular chemical properties of the side chains affect the interactions between amino acids in the protein, which ultimately determines the 3-dimensional shape and function of the protein. Some side chains are hydrophobic and tend to be buried in the interior of the protein away from water, while others are hydrophilic and tend to be on the surface of the protein where they can interact with water molecules. Therefore, side chains help determine the protein's shape and its solubility in water.
