So if you have too much methionine, you'd have too many methyl groups and you could accelerate aging.

所以，如果甲硫酸铵过多，甲基组就多，甲基组一多就会加速衰老过程。

For methionine to stimulate mTOR, it needs to donate a methyl group.

甲硫酸铵要激霉素靶白（mTOR）的作用就必须“捐献”出一个甲基组。

So, once methionine donates that methyl group, it becomes homocysteine.

所以，一旦甲硫酸铵“捐献”出甲基组，就会变成巯基丁氨酸。

And to your cells, the cysteine-methylmercury combo looks pretty much exactly like methionine.

对你的细胞来说，半胱氨酸-甲基汞组看起来非常像氨酸。

Methionine is the rare amino acid that contains sulfur, an element known for its pungent odor.

甲硫氨酸是一种稀有氨基酸含有硫，一种含有刺激性气味的元素。

Sometimes the condition comes about just because you've eaten too much methionine, which is in protein-rich foods, like meat and cheese.

所以产生体味的原因就是你吃了太多的甲硫氨酸，存在于高白食物中，比如肉和奶酪。

Methionine is very important for humans and animals.

甲硫氨酸对人类和动物都非常重要。

We now know that methylmercury gets through by disguising itself as a super important component of proteins — the essential amino acid methionine.

我们现在知道甲基汞是通过伪装成白质中极其重要的成分——必需氨基酸氨酸来通过屏障的。

According to the study, the amount of methionine in the corn kernels increased by about 57 percent.

根据这项研究，玉米粒中氨酸的含量增加了约 57%。

In your body, creatine is normally made in your liver, kidneys, and pancreas from parts of the amino acids glycine, arginine, and methionine.

在你的体内，肌酸通常是由你的肝脏、肾脏和胰腺中的氨基酸甘氨酸、精氨酸和氨酸组成的。

In severe cases, the inability to process methionine can lead to neurological problems and muscle weakness, among other problems in the nervous system.

在严重的例子中，处理甲硫氨酸的无能会导致神经性的障碍肌无力和其他神经系统的问题。

Again, treatment usually involves avoiding foods that contain methionine, as well as taking supplements to make sure that the body is getting what it needs.

同样的治疗方法通常包括避免含有甲硫氨酸的食物，同时吃一些能保证身体需要的营养品。

But if the cause is genetic, it can be due to mutations in one of several genes that are responsible for making the enzymes that help break down methionine.

但是如果起因是基因，可以被归咎于一些能够生成酶促使分解甲硫氨酸的基因突变。

The thing about methionine is that it's really easily absorbed across the almost-impenetrable placental barrier, as well as the similar barrier that's supposed to protect the brain.

氨酸很容易被几乎无法穿透的胎盘屏障吸收，以及保护大脑的类似屏障吸收。

So if you're getting methionine from muscle meat, it's not an issue if you're eating other glycine-rich parts of the animal like connective tissue and skin, or drinking bone broth.

所以，如果从肉食中摄入了甲硫酸铵，但同时又吃了富含甘氨酸的动物结缔组织、皮肤或者喝了骨头汤，则不会有任何问题。

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.

基本氨基酸，简称 EAA，是我们身体需要但不能自己产生的氨基酸，其中有 9 种：组氨酸，异亮氨酸，亮氨酸，赖氨酸，氨酸，苯丙氨酸，苏氨酸，色氨酸和缬氨酸。
