多肽亞鐵得抗氧化特性

多肽被證實可當做抗氧化劑使用，其結(jié)合人體產(chǎn)生的自由基，起到保護身體作用。例如，從羊奶酪蛋白中提取的多肽和從鱸魚皮中提取的多肽，都被證實有強氧化性。有研究表明，當多肽與金屬離子螯合時，多肽的序列以及空間結(jié)構(gòu)會發(fā)生變化，螯合過程中暴露出的氨基酸可能含有更多可為DPPH自由基提供電子或質(zhì)子的基團。將蛋黃蛋白多肽和亞鐵離子螯合發(fā)現(xiàn)，蛋黃蛋白多肽亞鐵離子螯合物對于DPPH的清除率IC₅₀為0.41 mg/ml，蛋黃蛋白多肽組分的清除率為5.40 mg/ml，這說明多肽與鐵離子螯合后其抗氧化活性顯著提高。ABTS自由基清除能力表明抗氧化物質(zhì)的總抗氧化能力。研究發(fā)現(xiàn)，小米糠球蛋白多肽-亞鐵螯合物的ABTS自由基清除能力顯著高于小米糠球蛋白多肽的，表明小米糠球蛋白多肽與亞鐵離子螯合后可以提高其總抗氧化能力

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
