Question
Chapter 24, Problem 4P
Interpretation Introduction
Interpretation:
The common methyl donor in the cell should be determined.
Concept introduction:
Amino acid synthesis is the biochemical process by which amino acids are synthesized. Organisms are not able to synthesize all amino acids. Humans can synthesize only 11 amino acids out of the 20 amino acids. These amino acids are termed as the non-essential amino acids, and the remaining amino acids are termed as the essential amino acids.

. Studies on CAMP actions in cultured cells usually involve adding to the cell
culture not CAMP, but dibutyryl CAMP (see structure). Why is this structural
modification necessary? How could you test the premise that di-Bu-CAMP
has the same biochemical effects as CAMP?
