7a. Glutathione (GSH) is a cys-containing tripeptide with the sequence Y-glu-cys-gly. The y- glu-cys means that the first peptide bond is between the y-carboxylate group and not the a-carboxylate group that is more typical. Draw the structure of glutathione. 75. GSH helps cells cope with oxidative stress (e.g. peroxides) by becoming oxidized in place of other biomolecules: 2 GSH +R-O-O-H (a peroxide) -> GSSG + ROH (an alcohol) + H2O Draw the structure of oxidised glutathione.
