(a) Process for the production of the zinc-binding peptides (IMAC-ZBP) from whey proteins (WPI). (b) Zinc-binding capacity and (c) ADAM17 inhibitory activity of WPH-Esp, its < 1 kDa fraction and IMAC-ZBP. Bars with different letters are significantly different mean values (P < 0.05). WPH-Esp, whey protein hydrolysate produced with Esperase
