since at least the amnestic effect of gamma-endorphin is similar to that of beta-endorphin , and gamma-endorphin is a possible metabolite of beta-endorphin by limited proteolysis of the carboxyl-terminal amino acid , it is suggested that at least some effects of beta-endorphin on memory may be mediated by its proteolysis product , gamma-endorphin .
