One last factor in Ketosis preserving muscle is leucine.

酮症最后一个储存能量的要素是亮氨酸。

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

没有这种酶，亮氨酸只能被部分分解。

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

当你处于酮症状态时，空腹的血液中亮氨酸水高。

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亮氨酸时，就产生这种酸。

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

氨酸，丙氨酸，缬氨酸，亮氨酸全都是非极性的，这就是你如何征服考试的秘诀啦！

Corn is actually very high in leucine.

玉米中亮氨酸含量际上非常高。

Well, it'll probably track with plasma leucine.

嗯，它可能追踪血浆亮氨酸。

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

通过亮氨酸示踪观察，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%。

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

而亮氨酸是一种在体内起合成代谢作用的，关键性支链氨基酸，所以它能保护体内脂肪较少的肌肉块。

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，蛋氨酸，苯丙氨酸，苏氨酸，色氨酸和缬氨酸。

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.

他发现在我们情绪化的眼泪中——不是我们日常的， 比如打哈欠的眼泪，而是我们情绪化的眼泪——有高浓度的压力荷尔蒙和亮氨酸脑啡肽， 我的舌头容易理解的是内啡肽。
