问题 在下列哪种情况下,蛋白质溶液的稳定性最差?(  )
选项 A.溶液pH>pI B.溶液pHC.溶液pH=pI D.溶液pH=7.4
答案 C
解析 参阅第15、16题解答。在pH=pI的溶液中,蛋白质成为兼性离子,净电荷为0,降低了蛋白质的稳定性。

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
