The reaction showing 2,4-dinitrofluorobenzene which could be used to identify the n-terminal amino acid of VAG is to be written. Further, the product of hydrolysis, when VKG is treated with 2,4-dinitrofluorobenzene, is to be identified. Concept introduction: The Sanger N-Terminal analysis is a method for sequence analysis of amino acid using 2,4-dinitrofluorobenzene (DNFB). The nucleophilic aromatic substitution reaction occurs when a polypeptide and DNFB react in mildly basic solution. The subsequent hydrolysis gives a mixture of amino acids with the N-terminal amino acid labeled with a 2,4-dinitrophenyl group.

Glutathione (GSH) is a tripeptide that serves as a mild reducing agent to detoxify peroxides and maintain the cysteineresidues of hemoglobin and other red blood cell proteins in the reduced state. Complete hydrolysis of glutathione givesGly, Glu, and Cys. Treatment of glutathione with carboxypeptidase gives glycine as the first free amino acid released.Treatment of glutathione with 2,4-dinitrofluorobenzene (Sanger reagent, Problem 24-21, page 1246), followed bycomplete hydrolysis, gives the 2,4-dinitrophenyl derivative of glutamic acid. Treatment of glutathione with phenylisothiocyanate does not give a recognizable phenylthiohydantoin, however.(a) Propose a structure for glutathione consistent with this information. Why would glutathione fail to give a normalproduct from Edman degradation, even though it gives a normal product from the Sanger reagent followed byhydrolysis?(b) Oxidation of glutathione forms glutathione disulfide (GSSG). Propose a structure for glutathione disulfide, and…
