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

它含有色氨，即一种在大脑中用来生血清化学物质。

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

酪氨是合成多巴胺、去甲肾上腺所须；色氨是合成神经递质血清所须。

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

一种对大脑特别重要物是氨基色氨。

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

" Numerous studies over the past decade have illustrated the importance of tryptophan, " says Dinan.

“过去十年大量研究已经说明了色氨重要性， ” 迪南说。

The brain needs a constant supply of tryptophan metabolites, as they are the building blocks for the mood-regulating hormone serotonin.

大脑需要持续供应色氨代谢物， 因为它们是情绪调节激血清组成部分。

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.

第三个研究方向取决于血清是由色氨制成事实，色氨是一种人体无法合成物质， 因此须从食物中摄取。

Tryptophan in our diet is broken down – by a group of gut microbes called bifidobacteria – into smaller metabolites that can cross the blood-brain barrier.

我们饮食中色氨被一组称为双歧杆菌肠道微生物分解成更小代谢物， 可以穿过血脑屏障。

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.

基本氨基，简称 EAA，是我们身体需要但不能自己生氨基，其中有 9 种：组氨，异亮氨，亮氨，赖氨，蛋氨，苯丙氨，苏氨，色氨和缬氨。

" If you take patients who have recovered from depression and you deplete their brains of tryptophan, their depression will reoccur within a really short period of time, within minutes to hours" .
