问题 转化糖酶可水解
选项

A.α-葡萄糖苷键
B.β-葡萄糖苷键
C.β-去氧糖苷键
D.β-果糖苷键
E.N-苷键

答案 D
解析 本题考查苷键的酶水解。常用的酶有:①β-葡萄糖苷水解酶,如苦杏苷酶,可以水解β-葡萄糖苷;②β-葡萄糖苷水解酶,如麦芽糖酶,可以水解β-葡萄糖苷键;③β-果糖苷水解酶,如转化糖酶,可以水解β-果糖苷键而保留其他苷键结构。故正确答案为BAD。

错误啦!

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.
