Annotation	Striking differences between the reduced and oxidized peptides were obtained by constant current chronopotentiometric stripping analysis at hanging mercury drop electrode (HMDE). Peptides yielded electrocatalytic peak H at highly negative potential (ca. -1.75 V). Reduced peptides adsorbed at positively charged HMDE produced substantially higher peaks H than the oxidized forms.
