One reason the M.O.A., the organic analyzer is so impressive is that it tests not just for the presence of amino acids but also for the handedness of amino acids.

M.O.A 这种有机分析器令人印象深刻的原因之一是：它不仅检验了氨基酸是否存在，而且还测试出了氨基酸的旋向性。

If amino acids are found, it would be especially interesting if they show a prevalence of one type of handedness, either left, like amino acids on Earth, or right.

如果发现了氨基酸，并且它们普遍表现出同一种偏向性——要么像地球上的氨基酸一样是左旋的，要么是右旋的，那将会格外有趣。

These amino acids come mainly from the food we eat (humans cannot synthesize all the amino acids we need and therefore must obtain the others, called "essential" amino acids, from food).

这些氨基酸主要来自我们吃的食物(人不能合成所需的所有氨基酸，因此改组从食物中获取其他的“基本”氨基酸)。

There is also early evidence suggesting that amino acids may also exist in the space between stars.

The plants can be deficient in certain things, especially fat soluble vitamins that come from meat and from essential amino acids.

植物中缺乏某些物质,特别是脂溶性维生素,那些只能从肉类和必需氨基酸中获得

You could read through this sequence and you could figure out what the sequence of amino acids would be.

因此你可以读一段序列,并推算出,对应的氨基酸序列

Most proteins are broken down into small peptides of between two and six amino acids or into single amino acids.

Neither does standard genetic engineering, in which some amino acids in the plug are swapped for other natural amino acids.

Of the 64 possible codons, 61 correspond to particular amino acids though several amino acids have more than one codon, since natural proteins consist of only 20 sorts of amino acid.
