Question
Draw the most common ionization form of Aspartic Acid at pH 2.90.
a. Based on your drawing, what kind of noncovalent side chain interactions could
aspartic acid participate in (with other amino acids) at pH 2.90?
Hydrogen bonds
b. Use the Henderson Hasselbach equation to calculate the ratio of base/acid for
aspartic acid's side chain at pH 2.90. Does this ratio make sense? Refer back to your
drawing and explain your answer.
