Abstract
En 中文
• Peptides from tilapia scale and sunflower meal proteins show Cu2+-driven assembly • Cu2+ coordination modulates peptide self-assembly in a sequence-dependent pattern. • Bioinspired peptides from food decrease level of Cu2+-induced ROS in C. elegans. • Pep1.GHRGFSGL exhibits the highest antioxidant capacity and binding ability. • Pure peptides provide mechanistic insight into behaviors observed in hydrolysates.
