Consider a chemical reaction of the type A + B → C followed by A + C → D in which two reactants A and B formed a mixture of C and D . The object was to obtain the maximum for C subject to the condition that the yield of D should not exceed 20% since more than this ...
David Evans, 60, is a chemistry professor at the Beijing University of Chemical Technology (BUCT). Tall and paunchy, he always wears a long white lab coat, a pair of safety goggles and a smile on his face before the camera. Some web users say he looks just like the "grandpa of KFC....

我们接下来讲一下chemical reaction. 对于一个化学反应AB + CD → AC + BD, AB和CD是这个酶的substrate,或者称为substrate. 我们得到的AC和BD就是产物(product) 如图所示,底物所含有的总能量和产物所含有的总能量是不同的。 如果底物含有的总能量大于产物...
In chemistry, molecules are often represented by molecular linear notations, and chemical reactions are depicted as sequence pairs of reactants and products. However, this approach does not capture atomic and bond changes during reactions. Here, we present ReactSeq, a reaction description language ...
