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

酪酸是合成多巴胺、去甲肾上腺素所必须的；色酸是合成神经递质血清素所必须的。

Essential amino acids, or EAAs, are amino acids that our body needs but cannot produce on its own, and there are 9 of them: Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

酸，简称 EAA，是我们身体需要但不能自己产生的酸，其有 9 种：组酸，异亮酸，亮酸，赖酸，蛋酸，苯丙酸，苏酸，色酸和缬酸。

They possess tryptophan, which helps create brain soothing hormones.

它们拥有色酸，帮助部释出舒缓荷尔蒙。

It contains tryptophan, a chemical in the brain that is used to produce serotonin.

它含有色酸，即一种在大用来产生血清素的化学物质。

And then the second thing to understand about serotonin, before we get into the practical tips, is that serotonin is made from an amino acid called tryptophan.

在介绍实用技巧之前，关于血清素需要了解的第二点是，它是由一种名为色酸的酸合成的。

Dude, that turkey tryptophan is really getting to me, man.

兄弟，那火鸡里的色酸真的让我不行了。

And tryptophan from our diets travels into the brain, where then the brain converts it into serotonin.

我们从饮食的色酸会进入大，然后被大转化为血清素。

And so if we are not getting enough tryptophan through our diet, then we won't be able to make enough serotonin in the brain.

因此，如果我们的饮食没有入足够的色酸，我们就无法在大产生足够的血清素。

One particularly important product for the brain is the amino acid tryptophan.

一种对大特别重要的产物是酸色酸。

And in that way, they... What's tryptophan?

这样一来， 它们… … 色酸是什么呢？

Dude, that turkey tryptophan is really gettin' to me, man.

伙计，火鸡色酸真的让我着迷，伙计。

It's made from a amino acid called tryptophan.

它是由一种名为色酸的酸制成的。

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

你会看到色酸、酪酸、苯丙酸、醌类气体、乳酸、胆固醇等成分。

It's produced by bacteria in the gut when breaking down tryptophan.

它是由肠道细菌分解色酸时产生的。

For example, the essential amino acid, we'll just pick a brain one, tryptophan for serotonin production, or threonine for mucin production in the gut, which helps the gut lining, or, you know, take your pick, phenylalanine.

例如， 必需酸，我们随便选一个， 色酸用于血清素的生成，或者苏酸用于肠道黏液的生成，这有助于保护肠壁，或者是苯丙酸。

So, you know, the story related to turkey and feeling sleepy, it's not, you know, that far-fetched in a sense that yes, turkey is a good source of tryptophan.

所以，你知道，关于火鸡和感到困倦的故事，在某种意义上并不是那么牵强，因为确实，火鸡是色酸的良好来源。

A third line of research depends on the fact that serotonin is made from tryptophan, a substance the body cannot synthesise, and so must ingest from food.

第三个研究方向决于血清素是由色酸制成的事实，色酸是一种人体无法合成的物质， 因此必须从食物。

Your general health illnesses ranging from Parkinson's disease, altered level piracy and tryptophan to diabetes sugars and fingermeiling leave abundant metabolic traces.

你的总体健康状况，从患有帕金森病、改变的水平海盗和色酸到糖尿病和手指迷航，都会留下丰富的代谢痕迹。

And yes, tart cherry juice tends to contain melatonin, certain types of nuts, milk contains tryptophan, as does smoked salmon, turkey.

而且是的， 酸樱桃汁通常含有褪黑激素，某些类型的坚果和牛奶含有色酸，熏三文鱼和火鸡也含有色酸。

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酸，其含有大约两到三百毫克的色酸和酪酸。
