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

酪氨酸是合成多巴、去甲肾上腺素所必须的；色氨酸是合成神经递血清素所必须的。

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

酪氨酸接着会被转化成对大脑正常的发育和功能都很重要的神经递。

Of these substances, the most important is tyrosine.

在这中， 最重要的是酪氨酸。

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

而这正是酪氨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.

你会看到色氨酸、酪氨酸、苯氨酸、醌类气体、乳酸、胆固醇等成分。

What if I had a deficiency in phenylalanine or tyrosine?

如果我缺乏苯氨酸或酪氨酸会怎样？

And then I would take bromantain to upregulate tyrosine hydroxylase.

然后我会服用来上调酪氨酸羟化酶。

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

我们还知道， 葡萄糖峰值会影响酪氨酸水平，而酪氨酸是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，在酪氨酸羟化酶（TH）的帮助下，酪氨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，在多巴能神经元内部，多巴是通过两个步骤合成的从氨基酸酪氨酸开始。

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氨基酸，其中含有大约两到三百毫克的色氨酸和酪氨酸。

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-酪氨酸和500毫克D-L-苯基氨酸，后者作为多巴的前体。

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，乳制品、干豆类和鸡蛋都含有酪氨酸，这是一种有助于在体内传播多巴的重要氨基酸。

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.

因为它含有酪氨酸，酪氨酸是一种帮助合成神经传递的基酸。因此如果你在睡前食用蛋白类食品，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，由酪氨酸羟基化形成的L-多巴通过酶快速脱羧另一种称为芳香族L-氨基酸脱羧酶（AADC）的神经递多巴。

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 酪氨酸激酶结构域（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种氨基酸组成，这氨基酸是蛋白的组成成分，但起作用的部分只有三个：赖氨酸、谷氨酸和酪氨酸。剩下的酶是包装的。
