A cytosolic protein has an important alpha amino group. The pKa of this group is approximately 8 when exposed to water outside of a protein. 1. What would happen to the pKa if this group was instead buried in the hydrophobic interior of the protein? Explain. 2.

How would the pKa of this alpha amino group compare with the pKa of the alpha amino group in the hydrophobic interior of the protein without a nearby Asparagine residue to form this ionic bond? Explain.
