The structure for glutathione that is consistent with the given information and the reason corresponding to the fact that glutathione fails to give a normal product from Edmann degradation, even though it gives a normal product from the Sanger reagent followed by hydrolysis. Interpretation: The structure for glutathione that is consistent with the given information is to be shown and the reason corresponding to the fact that glutathione fails to give a normal product from Edmann degradation, even though it gives a normal product from the Sanger reagent followed by hydrolysis is to be stated. Concept introduction: The process in which a proper series of amino acids is maintained peptide chain is known as Edmann degradation. This process includes the labelling of terminal amino residue followed by the cleavage of this terminal amino residue from the peptide chain. The peptide bonds between other amino acids do not get disturb during this process.
