Tyrosine is needed to synthesize dopamine and norepinephrine, and tryptophan is needed to synthesize the neurotransmitter serotonin.

酸合成多巴胺、去甲肾上腺素所必须的；色酸合成神经递质血清素所必须的。

Tyrosine is then turned into neurotransmitters important for normal brain development and function.

酸接着会被转化成对大脑常的发育和功能都很重要的神经递质。

Of these substances, the most important is tyrosine.

在些物质中， 最重要的酸。

And that's where the tyrosine hypothesis started coming up.

而酸假设开始出现的地方。

And you'll see tryptophan, and tyrosine, and phenylalanine, and quinone gas, and lactic acid, cholesterol.

你会看到色酸、酸、苯酸、醌类气体、乳酸、胆固醇等成分。

What if I had a deficiency in phenylalanine or tyrosine?

如果我缺乏苯酸酸会怎样？

And then I would take bromantain to upregulate tyrosine hydroxylase.

然后我会服用溴抗胺来上调酸羟化酶。

We also know that glucose spikes impact tyrosine levels, and tyrosine is an important molecule that regulates our mood.

我们还知道， 葡萄糖峰值会影响酸水平，而酸一种调节我们情绪的重要分子。

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

首先，在酸羟化酶（TH）的帮助下，酸也转化为左旋多巴被称为左旋多巴。

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

所以，在多巴胺能神经元内部，多巴胺通过两个步骤合成的从基酸酸开始。

I have another supplement that's called cognitive aminos that just basically has two to three hundred milligrams of like tryptophan, tyrosine.

我还有一种补充剂叫做认知基酸，其中含有大约两到三百毫克的色酸和酸。

So what I did is I took I took one gram of L-tyrosine, 500 milligrams of D-L-phenylalanine just for precursor for the dopamine.

所以我服用了1克L-酸和500毫克D-L-苯基酸，后者作为多巴胺的前体。

When it comes to food, dairy products, dried pulses and eggs all contain tyrosine, an essential amino acid which contributes towards spreading dopamine around the body.

说到食物，乳制品、干豆类和鸡蛋都含有酸，一种有助于在体内传播多巴胺的重要基酸。

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.

因为它含有酸，酸一种帮助合成神经传递物质的胺基酸。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，由酸羟基化形成的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）的神经递质多巴胺。

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 酸激酶结构域（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% 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.

醛缩酶A由350种基酸组成，些基酸蛋白质的组成成分，但起作用的部分只有三个：赖酸、谷酸和酸。剩下的酶包装的。
