5. Biomolecular engineers, such as Prof. Sandor Vajda in the BME department, are interested in how proteins fold and attain their native conformation. Consider a generic 50-kDa protein. Let's say each peptide link between amino acids has three possible orientations (i.e., three possible bond angles). A) Estimate the number of possible protein conformations. The average molecular weight of an amino acid is approximately 110 Da. B) Why is it impractical to analyze the behavior of the protein by using the protein's exact partition function? C) Propose a method to obtain an approximate partition function that can be used to analyze the protein's behavior
