The mismatch in question revolves around a molecule called carnitine.

疑问焦点集中于一种称为左旋肉碱分子。

That suggests the vegan's particular gut flora—adapted to his usual meat-free diet—did not contain species that can digest carnitine.

这表明素食者特殊肠道菌群――适应无肉饮食――不含有可消化左旋肉碱种类。

This diet resulted in high levels of both carnitine and TMAO in the volunteers' blood.

该食谱使得志愿者血液中左旋肉碱和TMAO都处高水平。

The principal difference they found turned out to be levels of L-DOPA.

们发现主要区别于左旋多巴水平。

Alright the next dopamine-directed class of therapies are inhibitors of COMT, catecholamine-O-methyltransferase, which is an enzyme that degrades dopamine and levodopa.

下一个针对多巴胺治疗药物是COMT抑制剂；COMT，即儿茶酚胺-O-甲基转移酶，是一种可以降解多巴胺和左旋多巴酶。

And observing a left spinning particle on one side of the world would make the other particle on the other side spin right.

一侧观察一个左旋粒子会使另一侧另一个粒子右旋。

Less commonly, babies can have levo-transposition of the great arteries, or l-TGA, with levo meaning that the aorta's primarily to the " left" of the pulmonary artery.

更少见地，宝宝可能会有左旋-大动脉转位，即L-TGA，左旋意思是主动脉主要位于肺动脉左侧。

They're right–handed with only rare exceptions, and when by chance a shell's spiral is left–handed, collectors will pay its weight in gold for it.

除极少数例外， 它们都是右旋，当碰巧贝壳螺旋是左旋时，收藏家会花上同等重量黄金来买它。

Experiments in mice confirmed the broader hypothesis: TMAO production relies on microbes that digest carnitine, and prolonged consumption of that chemical by susceptible mice leads to atherosclerosis.

产生TMAO需要能消化左旋肉碱细菌参与，易患病老鼠如果长期食用左旋肉碱会导致动脉粥样硬化。

Dopamine itself can't cross the blood-brain barrier, but its precursor levodopa can, and once in the brain, levodopa is converted to dopamine by dopa decarboxylase, most importantly within the remaining nigrostriatal neurons.

多巴胺本身不能通过血脑屏障，但它前体左旋多巴可以，一旦进入脑中，左旋多巴就会被多巴脱羧酶转换为多巴胺，尤其是残存黑质纹状体神经元内。

Leads I and aVL, along with two of the chest leads, V5 and V6, are all considered " lateral" leads and they're near the lateral wall of the heart which receives blood from the left circumflex artery.

I、aVL以及V5和V6导联，被认为是“侧壁导联”，因为它们靠近心脏侧壁，这里接受左旋支动脉血液供应。
