MtoZ Biolabs provides comprehensive Antioxidant Peptides Screening Services utilizing advanced molecular display technologies and LC-MS/MS-based peptide identification. Our platform enables rapid and accurate discovery of peptides with antioxidant activity from both natural and synthetic libraries, supporting research in pharmaceuticals, nutrition, and functional food development.
What Is Antioxidant Peptide?
Antioxidant peptides are short bioactive sequences capable of protecting cells and tissues from oxidative stress. Their antioxidant activity mainly arises from three mechanisms:
🔸Free radical scavenging
🔸Inhibition of lipid peroxidation
🔸Chelation with metal ions
By neutralizing free radicals and preventing oxidative chain reactions, these peptides help maintain cellular integrity and functionality. They are increasingly recognized for their ability to delay lipid oxidation in food systems and to protect biological systems from oxidative damage, contributing to overall health maintenance and disease prevention.
