Question
Chapter 7, Problem 45RE
Interpretation Introduction
Interpretation:
The importance of the pKa value of histidine 57 for its role in the mechanism of chymotrypsin action is to be discussed.
Concept Introduction:
The pKa (acid dissociation constant) value of any amino acid gives information about the acidity of the amino acid. A higher pKa value means that the amino acid is strongly acidic in nature.
pKa was introduced to determine the acidity of weak acids in the acid-base reactions that occur in aqueous solutions.
