The tertiary structure of a protein is a complex arrangement formed as the polypeptide chain folds and twists. The folding and twisting of the polypeptide chain is caused by different interactions between the side chains of the amino acids. The side chains of the amino acids also interact with the surrounding aqueous environment. Identify the different types of attractive forces or interactions present in the given tertiary structure of a protein molecule. Drag the appropriate labels to their respective bins.
