Which of the following definitions best describes '(E)-1-(glutathione-S-yl)-omega-(methylthio)alkylhydroximate(1-)'?

A. An S-substituted glutathione(1-) obtained by deprotonation of the the two carboxy groups and protonation of the amino group of S-(1-hydroxy-2-methylbut-3-en-2-yl)-glutathione; major species at pH 7.3.
B. An S-substituted glutathione(1-) obtained by deprotonation of the the two carboxy groups and protonation of the amino group of any (E)-1-(glutathione-S-yl)-omega-(methylthio)alkylhydroximate; major species at pH 7.3.
C. An S-substituted glutathione(1-) obtained by deprotonation of the the two carboxy groups and protonation of the glutamyl amino group of S-(2,4-dinitrophenyl)glutathione. Major microspecies at pH 7.3.
D. An S-substituted glutathione(1-) obtained by deprotonation of the the two carboxy groups and protonation of the amino group of S-(2-formyl-2-methylbut-3-en-2-yl)-glutathione; major species at pH 7.3.

Answer: An S-substituted glutathione(1-) obtained by deprotonation of the the two carboxy groups and protonation of the amino group of any (E)-1-(glutathione-S-yl)-omega-(methylthio)alkylhydroximate; major species at pH 7.3.
