1问题王彬[山东省东营市河口区一中(257200)]变性之后的蛋白质是可以和双缩脲试剂反应的,然而蛋白质和双缩脲试剂反应后,蛋白质变性了吗?这个反应是否改变了蛋白质的空间结构?2讨论任智安[北京市通州区永乐店中学(101105)]应该会发生变性。因为强碱和重金属都会引起蛋白质变性,而蛋白质鉴定实验需要强碱性环境,同时Cu~(2+)会与肽键发生络合反应,重新形成电子配对和化学键,改变了蛋白质的空间结构。
1 problem Wang Bin [Dongkou City, Shandong Province estuary one (257200] protein after denaturation and biuret reagents can react, but after the reaction of protein and biuret protein denaturation it? This response is changed The spatial structure of the protein? 2 Discussion Ren Zhi’an [Tongzhou District, Beijing Yongledian Middle School (101105)] degeneration should occur. Because both alkali and heavy metals cause protein denaturation, the protein identification experiment requires a strong alkaline environment. At the same time, Cu 2+ complexes with peptide bonds to form electronic pairs and chemical bonds, which changes the spatial structure of proteins.
