Abstract Sulfur-containing amino acids such as methionine, cysteine, and taurine are present in animals and plants with biological functions. The aim of this study was to determine the antioxidant activities of representative sulfur-containing amino acids using various in vitro antioxidant assays including radical scavenger activities against DPPH , ABTS , and superoxide radicals, ferric reducing antioxidant power, hydrogen peroxide scavenging activity, and metal chelating activities. Of the three sulfur-containing amino acids, cysteine had the highest DPPH , ABTS , and O2− radical and H2O2 scavenging activities, FRAP, and metal chelating activities except for Fe2+ chelating. However, methionine and taurine failed to show DPPH or ABTS radical scavenging activity. Based on the results of the present study, sulfur-containing amino acids with excellent antioxidant abilities might be useful for the food processing industry as antioxidant additives to extend shelf-life of food or food products and offer beneficial pharmacological effect against cell damage caused by oxidative stress.

含硫氨基酸的体外抗氧化作用

摘要 蛋氨酸、半胱氨酸、牛磺酸等含硫氨基酸存在于具有生物学功能的动植物体内。本研究的目的是使用各种体外抗氧化试验来确定代表性含硫氨基酸的抗氧化活性,包括对 DPPH 、ABTS 和超氧自由基的自由基清除活性、铁还原抗氧化能力、过氧化氢清除活性和金属螯合。活动。在三种含硫氨基酸中,除 Fe2+ 螯合外,半胱氨酸具有最高的 DPPH 、ABTS 和 O2- 自由基和 H2O2 清除活性、FRAP 和金属螯合活性。然而,蛋氨酸和牛磺酸未能显示出 DPPH 或 ABTS 自由基清除活性。根据目前的研究结果,
