Of these substances, the most important is tyrosine.

在这些物质中， 最重要的是酪。

So, here, inside this dopaminergic neuron, dopamine is synthesized in a two-step process starting with the amino acid tyrosine.

所以，在胺能神经元内部，胺是通过两个步骤合成的从酪开始。

First, with the help of enzyme tyrosine hydroxylase (TH), tyrosine gets converted to L-dopa, also known as levodopa.

首先，在酪羟化（TH）的帮助下，酪也转化为左被称为左。

That, along with it containing tyrosine, an amino acid that aids neurotransmitter production, may make it hard to get some rest if you have a bunch of protein before bed.

因为它含有酪，酪是一种帮助合成神经传递物质的胺。因此如果你在睡前食用蛋白质类食品，便可能造成睡眠困难。

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，由酪羟化形成的L-通过快速脱羧另一种称为芳香族L-脱羧（AADC）的神经递质胺。

ROS1 rearrangement ROS1 rearrangements lead to fusions of the ROS1 tyrosine kinase domain (on chromosome 6) with partner genes, usually on other chromosomes, and occur in approximately 2% of NSCLCs.

ROS1 重排 ROS1 重排导致 ROS1 酪激结构域（位于 6 号染色体上）与伴侣因（通常位于其他染色体上）融合，发生在大约 2% 的 NSCLC 中。

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A由350种组成，这些是蛋白质的组成成分，但起作用的部分只有三个：赖、谷和酪。剩下的是包装的。
