Cysteine-rich peptide for chiral self-assembly: a multi-functional antioxidant with novel SH-mediated ROS-responsive disassembly from natural medicine

), representing a rarely reported form of ROS responsiveness mediated by the oxidation of natural cysteine thiol groups. Overall, this study introduces a natural, multifunctional antioxidant supramolecular system that shows strong potential for addressing complex oxidative stress-related conditions, with inherent biosafety supported by its all-L-amino-acid composition and hierarchically propagated chiral architecture.
