Zinc Chelates from Low-Molecular-Weight Donkey-Hide Gelatin Peptides: Preparation, Characterization, and Evaluation of In Vitro Antioxidant Activity

This study synthesized a low-molecular-weight donkey-hide gelatin peptide–zinc chelate (LMW DHGP–Zn) using peptides derived from donkey-hide gelatin. Under optimized conditions (zinc concentration of 32 mg/mL, peptide-to-zinc mass ratio of 8:1, pH 6.5, 60 °C, 70 min), a maximum chelation rate of 41....
