This study investigated the structure–activity relationships between SePEPs (selenium-enriched peptides) and PEPs (selenium-free compared antioxidant activities of PEPs. The results showed that exhibited higher activity than at same molecular weight, with weights 0–3500 Da exhibiting highest in vitro activity. Chelation selenium peptides led to a more compact structure increased particle density SePEPs. A spectroscopic analysis revealed new peaks redshifts SePEPs, along content hydrophobic amino acids interaction modeling indicated hydrogen bonding interactions primarily drove binding selenium-containing 1,1-diphenyl-2-picrylhydrazyl (DPPH). Moreover, solid-phase synthesized MSePGP significantly greater glutathione high concentrations. At 10 mg/mL, DPPH radical scavenging rate was 68.5 ± 2.2%. These findings provide theoretical basis for design synthesis selenium-enriched enhanced properties.
