多肽被证实可当做抗氧化剂使用，其结合人体产生的自由基，起到保护身体作用。例如，从羊奶酪蛋白中提取的多肽和从鲈鱼皮中提取的多肽，都被证实有强氧化性。有研究表明，当多肽与金属离子螯合时，多肽的序列以及空间结构会发生变化，螯合过程中暴露出的氨基酸可能含有更多可为DPPH自由基提供电子或质子的基团。将蛋黄蛋白多肽和亚铁离子螯合发现，蛋黄蛋白多肽亚铁离子螯合物对于DPPH的清除率IC₅₀为0.41 mg/ml，蛋黄蛋白多肽组分的清除率为5.40 mg/ml，这说明多肽与铁离子螯合后其抗氧化活性显著提高。ABTS自由基清除能力表明抗氧化物质的总抗氧化能力。研究发现，小米糠球蛋白多肽-亚铁螯合物的ABTS自由基清除能力显著高于小米糠球蛋白多肽的，表明小米糠球蛋白多肽与亚铁离子螯合后可以提高其总抗氧化能力

Polypeptide ferrous has antioxidant properties

Peptides have been shown to work as antioxidants, combining with free radicals produced by the body to protect the body. For example, peptides extracted from goat milk casein and peptides extracted from sea bass skin have been shown to be highly oxidizing. Studies have shown that when the peptide is chelated with metal ions, the sequence and spatial structure of the peptide will change, and the amino acids exposed during chelation may contain more groups that can provide electrons or protons for DPPH free radicals. After chelating egg yolk protein polypeptide and ferrous ion, it was found that the DPPH clearance rate of egg yolk protein polypeptide ferrous ion chelate was 0.41 mg/ml, and the clearance rate of egg yolk protein polypeptide component was 5.40 mg/ml, indicating that the antioxidant activity of polypeptide was significantly improved after chelating with iron ion. ABTS free radical scavenging capacity indicates the total antioxidant capacity of the antioxidant. It was found that the ABTS free radical scavenging ability of rice bran globulin polypeptide-ferrous chelate was significantly higher than that of rice bran globulin polypeptide, indicating that rice bran globulin polypeptide chelate with ferrous ion can improve its total antioxidant capacity
