Glycine, alanine, valine, leucine are all nonpolar assets and this is how you drop them in an exam.

酸，丙酸，缬酸，亮酸全都是非极性的，这就是你如何征服考试的秘诀啦！

When the SNARE proteins are cleaved, it prevents the release of inhibitory neurotransmitters like glycine and GABA.

一旦SNARE蛋白被破坏，酸和GABA性神经递质的释放将会被阻断。

But, we have an amino acid called glycine that acts as a buffer for too many methyl groups.

但是，人体中有一种名叫酸的酸，可抵消过量甲组带来的负面作用。

And all of those genes are related to glycine receptors.

所有这些因都与酸受体有关。

Creatine is a naturally occurring amino acid that our body itself makes from two other amino acids, arginine and glycine.

肌酸由其他两种体内的酸合成，即精酸和酸。

It begins in the mitochondria where succinyl CoA binds to glycine via delta-ALA synthase to produce delta-aminolevulinic acid, or ALA.

反应开始于线粒体，琥珀酰CoA通过δ-ALA合成途径，结合酸以δ-乙酰丙酸（ALA）。

Glycine is one of the brain's primary inhibitory neurotransmitters, meaning the signal it sends makes a neuron less likely to fire.

酸是大脑主要的性神经递质之一，这意味着它发出的信号使神经元不太可能被激活。

And glycine is the simplest of them all.

酸是其中最简单的。

The primary inhibitory neurotransmitters are GABA and glycine.

主要的性神经递质是GABA和酸。

And so then I got thinking, Okay, that's I guess possible if you have more glycine and proline.

然后我就想， 好吧，我想如果有更多的酸和脯酸的话， 这是可能的。

At least they've shown that glycine can go up in the plasma from taking it in.

至少他们已经证明，酸在血浆中的含量会因摄入而升高。

So why aren't we just suggesting that people take glycine instead of collagen?

那么为什么我们不建议人们服用酸而不是胶原蛋白呢？

But, we've found that some of the simplest organisms on earth use glycine in surprisingly similar ways.

但是，我们发现地球上一些最简单的生物以惊人的相似方式使用酸。

They carried mutations in those genes that made it harder for glycine to bind to receptors and send its inhibitory signal.

它们携带的因突变使得酸更难与受体结合并发出信号。

They have a very large amount of glycine.

它们含有大量的酸。

For most people, if you're startled or bumped, you get a reaction of neural activation, and glycine tends to immediately shut it down.

对大多数人来说，如果你受到惊吓或碰撞，你会得到神经激活的反应，酸往往会立即关闭它。

So 33% of collagen is glycine.

因此，33% 的胶原蛋白是酸。

This helped connect their symptoms to a neurotransmitter called glycine because we have a higher concentration of glycine receptors in the brainstem and spinal cord.

这有助于将他们的症状与一种叫做酸的神经递质联系起来，因为脑干和脊髓中酸受体的浓度更高。

And because there are glycine receptors that help signal to opposing muscle groups, it can help you control automatic reflexes from surprises or startles.

因为有酸受体帮助向相反的肌肉群发出信号，它可以帮助你控意外或惊吓的自动反射。

That's because glycine is one of only twenty amino acids essential to human life, and probably all life as we know it.

这是因为酸是人类生命必需的 20 种酸之一，可能是我们所知道的所有生命必需的。
