Like ethanol, butanol is an alcohol. That means each of its molecules contains an oxygen atom as well as the carbon and hydrogen found in an alkane.
和乙醇一样，丁醇也属于醇类，这说明每一个丁醇分子包括一个氧原子和直链烷烃里的那种碳原子、氢原子。
That means each of its molecules contains an oxygen atom as well as the carbon and hydrogen found in an alkane.
就是说每个分子也都含有氧原子以及在烷烃中存在的碳和氢。
To explore the role of the bridged N atom for a possible proton transfer in the active site of hydrogenase, we tried to introduce a hydrogen bond into a couple of designed molecules.
