Question
Chapter 24, Problem 15P
Interpretation Introduction
Interpretation:
Three different cofactors that act as carriers of one carbon unit.
Concept introduction:
Cofactors are the chemical compounds, basically, metallic ions, that are required by the enzymes to increase their metallic activities. There are two types of cofactors, organic cofactors, and inorganic cofactors. Organic cofactors include heme, and flavin groups, while inorganic cofactors are metallic ions.

a. Suppose that you have the peptide Ala-Gly-Tyr-His-Leu and you treat it with FDNB and then 6M HCl. Draw the structures of all the products that you will have in solution (assume all reactions to go to completion).
Prepare a schematic diagram and present it as though it were a Figure in a publication (scientific journal or textbook) The diagram should illustrate the interactions made between the key components of (a) total and (b) non-specific binding reactions. In preparing your diagram，you should reflect on the role of each of the components of the reaction mixtures, and why the subtraction of non-specific from total binding allows us to calculate specific binding. The diagram Legend should be brief but informative.
