Question
Chapter 25, Problem 7P
Interpretation Introduction
Interpretation:
To determine the C atom in chorismate which is radioactive.
Concept Introduction:
Amino acids- The organic compounds which join together to form proteins. Upon digestion of proteins or when they are broken, the amino acids are left behind.
PEP is derived from phosphate and enol of pyruvate. Through the shikimate pathway, it is used for chrosimate synthesis.

Chemical labeling of chymotrypsin by the compound tosylphenylalanine chloromethyl ketone (TPCK) modifies the His 57 in the
enzyme's active site. The structure of this derivative is shown below. TPCK inactivates the enzyme because the bulky addition
prevents it from cleaving nearby covalent bonds.
