One last factor in Ketosis preserving muscle is leucine.

酮症最后一个储存量的要素是亮氨。

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

当你处于酮症状态时，空腹的血液中亮氨水平会更高。

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

这酶十重要，因为解氨基白氨。

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

没有这酶，亮氨只被部解。

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

甘氨，丙氨，缬氨，亮氨都是非极性的，这就是你如何征服考试的秘诀啦！

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时，就会产生这。

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

正在做亮氨的氨基谱检测和蛋白质含量检测。

So leucine is uniquely stimulating to skeletal muscle.

所以亮氨对骨骼肌有独特的刺激作用。

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

然后说，好吧，也许亮氨没有进入细胞。

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

主要对于骨骼肌健康的是支链氨基，其中亮氨就是其中之一。

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

当你有足够的亮氨时，会触发肌肉蛋白合成。

So we looked at intracellular leucine.

因此们研究了细胞内的亮氨。

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

大多数蝙蝠食用的血液中含有预先经过化学标记的两氨基（亮氨或甘氨）中的一。

Skeletal muscle is sensitive to one of the amino acids, leucine.

骨骼肌对一氨基——亮氨敏感。

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小时内的数合成率等测量值降低了20%。

It does seem that ingesting 700 to 3000 milligrams of the essential amino acid leucine with each meal is important.

看来每次用餐摄入700到3000毫克的必需氨基亮氨是很重要的。

So what you're seeing here is now these meals are meeting a leucine threshold.

所以你现在看到的是这些餐食达到了亮氨阈值。

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

优质乳清蛋白的亮氨含量最高吗？

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的，关键性支链氨基，所以保护体内脂肪较少的肌肉块。

Is there a place for supplementing leucine and other branched chain amino acids specifically?

补充亮氨和其他支链氨基是否有其特定的位置呢？
