你们船在推进时螺旋浆是右旋还是左旋？

Stopped the magnesium, started iron dextran for severe anemia.

She is infused with 5 liters of water with 5% dextrose, known as glucose, or sugar.

我们给她输注了5升5%右旋糖，即葡萄糖或者简称糖。

Did you change her banana bag?

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 there is a little mini chemistry lesson in there, which is that there are right and left-handed molecules, basically.

这里面还有一点小化学课，就是基本上存在右旋和左旋分子。

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，无论是左旋还是右旋，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时，收藏家会花上同等重量的黄金来买它。

六个多月以来， 美国人一直在努力获得右旋苯丙胺（俗称阿得拉）和哌醋甲酯（利他林）等药物。

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题时，分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，有时也叫右旋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无线电波时， 他们会使用螺旋天线。
