Dr List worked on an enzyme called aldolase A. This catalyses what is known as the aldol reaction, an important way of forging molecular bonds between carbon atoms.

利斯特博士研究了一种名为醛缩酶A的酶，种酶催化所谓的醛缩反应，是一种在碳原子之间形成分子键的重要方式。

Aldolase A is made of 350 amino acids, the building blocks of proteins, but the bit that does the work consists of only three of these: lysine, glutamic acid and tyrosine. The rest of the enzyme is packaging.

醛缩酶A由350种氨成，些氨是蛋白质的成成分，但起作用的部分只有三个：赖氨、谷氨和酪氨。剩下的酶是包装的。
