Did you change her banana bag?

你换了她的电解质补? 停用镁 开始使用针对严重贫血症的铁右旋糖苷？

In fact, as naturalists have ventured to observe, " dextrality" is a well–known law of nature.

事实上，正如博物学家大胆观察到的那样，“右旋”是众所周知的自然法则。

And yet the chemistry of these building block units, amino acids and nucleobases is the same for left and right handed.

然而，这些构建生命的基础单元——氨基酸和核苷酸的化学性质，论是左旋还是右旋，都是相同的。

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.

除了极少数例外， 它们都是右旋的，当碰巧贝壳的螺旋是左旋的，收藏家会花上同等重量的黄金来买它。

In most cases, when it comes to that left-hand versus right-hand thing, The molecule cannot just easily go from the left-hand version to the right-hand version.

在大多数情况下， 当涉及到左旋和右旋的问，子不能轻易地从左旋形式转变为右旋形式。

This isn't good, and this situation is actually called complete TGA, or sometimes dextro-TGA or d-TGA, dextro meaning " right" , since in this case, the aorta's in front of and primarily to the right of the pulmonary artery.

这种情况不太妙，被称为完全TGA，有也叫右旋TGA或者d-TGA，dextro的意思是右旋的，因为这种情况下，主动脉在肺动脉的前面并且主要在肺动脉的右边。

Now, one example of a shape that would resonate differently with left-handed and right-handed circularly polarized light would be a helix, and in fact, people will use a helical antenna when they want to pick up on radio waves with just one-handedness.

现在，一个例子就是螺旋形， 它会以不同的方式与左旋和右旋圆偏振光发生共振。事实上，当人们想要接收单一手性的线电波， 他们会使用螺旋天线。
