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种基酸组成，这些基酸是蛋组成成，但起作用部只有三个：赖酸、谷酸酸。剩下酶是包装。

In the second step, the L-dopa formed by tyrosine hydroxylation is quickly decarboxylated by another enzyme called aromatic L-amino acid decarboxylase (AADC), to the neurotransmitter dopamine.

在第二步中，由酸羟基化形成L-多巴通过酶快速脱羧另一种称为芳香族L-基酸脱羧酶（AADC）神经递多巴胺。
