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.

基本基，简称 EAA，是我们身体要但不能自己产生的基，其中有 9 ：，异，，赖，蛋，苯丙，苏，色和缬。

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

甘，丙，缬，全都是非极性的，这就是你如何征服考试的秘诀啦！

This enzyme is important because it helps break down the amino acid leucine.

这酶十分重要，因为它能分解基白。

Plant sources of protein tend to be lower in branched-chain amino acids, they tend to be lower in essential amino acids, and tend to be lower in leucine.

植物来源的蛋白质往往支链基含量较低，必基含量较低，含量较低。

When you're in ketosis, you have a higher fasting blood leucine level.

当你处于酮症状态时，空腹的血液中水平会更高。

Measurements like fractional synthetic rate within 0 to 5 hours post-exercise were reduced by as much as 20 percent through leucine tracer observations.

通过示踪观察，诸如运动后0到5小时内的分数合成率等测量值降低了20%。

One last factor in Ketosis preserving muscle is leucine.

酮症最后一个储存能量的要素是。

The bacteria hiding out between your toes produce this acid when they're chomping away on leucine.

当隐藏在脚趾的细菌产生时，就会产生这。

There is, so far, no cure for isovaleric acidemia, but some treatments — like avoiding foods rich in leucine, and taking supplements of other, non-threatening amino acids — can help keep patients safe.

目前没有治疗异戊血症的方法，但是一些疗法——比如避免进食白过多的食物，从其他物质中，比如没有威胁的基，能够保证患者安全。

Without this enzyme, leucine can only be broken down part-way.

没有这酶，只能被部分分解。

And leucine is a key branch chain amino acid that has an anabolic effect on the body so it preserves lean body mass.

而是一在体内起合成代谢作用的，关键性支链基，所以它能保护体内脂肪较少的肌肉块。

In specific, Dr. Layne Norton explains that you need to go to greater lengths to get enough of that key muscle protein synthesis stimulating amino acid leucine if you are relying on plant sources of protein.

具体来说，莱恩·诺顿博士解释说，如果你依赖植物来源的蛋白质，你要吃得更多，以获得足够的关键肌肉蛋白质合成刺激基。

I am getting my amino acid leucine profile, protein count.

我正在做的基谱检测和蛋白质含量检测。

He found that inside of our emotional tears -- not our everyday, like, yawning tears, but our emotional tears -- there's high concentrations of stress hormones and leucine enkephalins, which, easier on my tongue, is endorphins.

他发现，在我们的情感泪水——不是我们日常那打哈欠时的眼泪， 而是情感泪水——中，含有高浓度的压力荷尔蒙和脑啡肽， 后者对我来说更容易说的就是内啡肽。

These are flagged up by lower than normal levels of things like leucine, glycerol and phenylalanine Your local environment breathing in polluted air has a marked impact on the profile of your metabolites.

这些标志是由、甘油和苯丙等物质低于正常水平引起的。你所处的环境，比如吸入污染的空气，会对你的代谢物谱产生显着影响。

The RDA for leucine, which is that essential amino acid, meaning we cannot make it, we must get it from the diet, is set at 2.7 grams per day.

的日推荐摄入量为2.7克， 这是一必基，意味着我们无法自行合成它， 必须通过饮食摄取。

Most bats consumed blood that had one of two amino acids (either leucine or glycine) chemically labelled beforehand.

大多数蝙蝠食用的血液中含有预先经过化学标记的两基（或甘）中的一。

Collagen protein is going to be least ideal for post-workout protein because of the fact that it's, you know, it lacks significant amounts of leucine, et cetera.

胶原蛋白是最不理想的运动后蛋白质，因为它缺乏大量的等。

And then I said, OK, well, maybe leucine isn't getting into the cell.

然后我说，好吧，也许没有进入细胞。

And my hypothesis was, well, however long leucine is elevated in the blood is going to be how long protein synthesis stays up.

我的假设是，血液中升高的时间长短决定了蛋白质合成维持的时间长短。
