Homework Answers
I believe the correct answer to be:;
Option B) Hydrophobic animoacid R groups are on the interior f the protein and hydrophillic groups are on the outside.
As hydrophillic parts of the polypeptide interact with the water while the hydrophobic part hides inside the structure.

Even though hydrophobic amino acids tend to be buried in the interior of a globular protein, polar neutral and polar charged amino acids are found in the interior of a globular protein as well. Recall Figure 4.26 of myoglobin. To see how this can happen, consider a model of a generic globular protein (below). The side chains of only seven of the amino acids are shown. 5. "DH" is a side chain that is a hydrogen bond donor "A" is...

1. Amino acids are considered to be either hydrophobic or hydrophilic as described by the relative polarity of their side chain. Consider a folded protein in an aqueous environment; where would the hydrophobic amino acids likely be found? -Tucked away in the middle of the folded protein -Randomly distributed throughout the protein -Exposed on the exterior surface of the folded protein 2. All proteins exhibit a primary, secondary, and tertiary structure, but not all proteins exhibit a quaternary structure. Describe...
