One last factor in Ketosis preserving muscle is leucine.

酮症最后一个储存能量的要素亮氨。

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

没有这种酶，亮氨只能被部分分解。

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

当你处于酮症状态时，空腹的血液中亮氨水平会更高。

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

甘氨，丙氨，缬氨，亮氨全都非极性的，这就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，就会产生这种。

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

这种酶十分重要，因为它能分解氨基白氨。

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，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.

而亮氨一种在体内起合成代谢作用的，关键性支链氨基，所以它能保护体内脂肪较少的肌肉块。

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，但一些疗法——比如避免进食白氨过多的食物，从其他物质中，比如没有威胁的氨基，能够保证患者安全。

The two missing links in the chain (a phenylalanine and a leucine, for aficionados) are encoded in the gene for ordinary tomcod AHR by six genetic “letters” that are missing from the DNA found in PCB-resistant Hudson tomcod.

普通的鲟鱼AHR由六个基因信号编码缺少两个氨基（苯丙氨和亮氨）的化学链形成，然而在耐PCB的哈得逊河鲟鱼DNA中很难找到。
