Of these substances, the most important is tyrosine.

在这些物质中， 最重要是酪。

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

首先，在酪化酶（TH）帮助下，酪也转化为左旋巴被称为左旋巴。

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

所以，在巴胺能神经元内，巴胺是通过两个步骤合从基酪开始。

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，由酪基化形L-巴通过酶快速脱羧另一种称为芳香族L-基脱羧酶（AADC）神经递质巴胺。

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，酪是一种帮助合神经传递物质胺基。因此如果你在睡前食用蛋白质类食品，便可能造睡眠困难。

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 酪激酶结构域（位于 6 号染色体上）与伴侣基因（通常位于其他染色体上）融合，发生在大约 2% 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.

醛缩酶A由350种基组，这些基是蛋白质组分，但起作用分只有三个：赖、谷和酪。剩下酶是包装。
