Structural Biochemistry/Enzyme Catalytic Mechanism

WebThe hydrogen ion functions as a catalyst. Two other examples are concerned with the production of 2,2,4-trimethylpentane from 2-methylpropene, again using an acid as the catalyst. One uses 2-methylpropane (Table 3) which yields the alkane directly. The other uses only 2-methylpropene.
