Our previous report showed that yam dioscorin and its peptic hydrolysates exhibit radical scavenging activities; however, the functions of these peptic hydrolases are still under investigation. In this study, the thiol-containing peptides derived from computer-aided simulation of pepsin hydrolysis of
