One last factor in Ketosis preserving muscle is leucine.

酮症最后一个储存能量要素是亮氨。

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

你处于酮症状态时，空腹血液中亮氨水平会更高。

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

没有酶，亮氨只能被部分分解。

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

甘氨，丙氨，缬氨，亮氨全都是非，就是你如何征服考试秘诀啦！

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

隐藏在脚趾细菌产生亮氨时，就会产生。

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

酶十分重要，因为它能分解氨基白氨。

And of these 3 BCAAs, by the far the most important is leucine.

在三支链氨基中，亮氨无疑是最重要一。

So leucine is uniquely stimulating to skeletal muscle.

所以亮氨对骨骼肌具有独特刺激作用。

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

然后我说，好吧，也许亮氨没有进入细胞。

Well, it'll probably track with plasma leucine.

嗯，它可能会追踪血浆亮氨。

Corn is actually very high in leucine.

玉米中亮氨含量实际上非常高。

Primarily for skeletal muscle health are the branch chain amino acids, leucine being one of those.

对于骨骼肌健康而言，主要是支链氨基，其中亮氨是其中之一。

And when you have enough leucine, it triggers muscle protein synthesis.

色氨足够时，它会触发肌肉蛋白合成。

So we looked at intracellular leucine.

因此我们研究了细胞内亮氨。

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

大多数蝙蝠食用血液中含有预先经过化学标记两氨基（亮氨或甘氨）中一。

And a quality whey protein would be the highest leucine available?

优质乳清蛋白亮氨含量最高吗？

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

通过亮氨示踪观察，诸如运动后0到5小时内分数合成率等测量值降低了20%。

And with about 3 grams of leucine per serving, whey protein most definitely can improve your gains at the gym.

而且每份含有约3克亮氨，乳清蛋白肯定能提升你在健身房锻炼效果。

Eggs, whey protein, eggs are going to be around nine percent leucine, you know, beef, chicken.

鸡蛋、乳清蛋白，鸡蛋中大约含有 9% 亮氨，你知道，牛肉、鸡肉也是如此。

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

而亮氨是一在体内起合成代谢作用，关键支链氨基，所以它能保护体内脂肪较少肌肉块。
