Outside of people with a rare genetic disorder known as phenylketonuria, phenylalanine and aspartic acid are generally safe to consume, since they're amino acids that exist in pretty much any protein source.

除了患有罕见遗传性疾病-苯丙酮尿症的人之外，其他人通常可以安全用苯丙氨和天冬氨，因为这两者是几乎存在于所有蛋白质中的氨基。

Similarly, there are peptidases which break down peptide chains into single amino acids.

It does make perfect evolutionary sense that we should have the ability to detect or taste glutamate because it is the amino acid which is most common in natural foods.

我们因该能发现或尝出谷氨盐因为谷氨盐就是未经加工的物中常见的氨基。

And it's really the identity of the amino acids, which letters are in that necklace, and in what order they are, what they spell out, that gives an enzyme its unique properties and differentiates it from other enzymes.

氨基的种类，也就是项链上的字母，及其排列、拼写的顺序，赋予了某种酶独特的属性，将其与其他酶区分开来。

It does make perfect evolutionary sense that we should have the ability to detect or taste glutamate because it is the minor acid which is the most common in natural foods.

因为谷氨盐是在自然物中很常见的氨基，所以我们能够发现并尝出它的味，化的角度看，这是说得通的。

And amino acids all have slightly different chemistries, each suited to slightly different jobs.

氨基的化学成分略有不同，每种氨基适合的工作也略有不同。

As an anti-inflammatory, it might decrease the number of amino acids that promote inflammation.

It contains all essential amino acids our body needs, and a lot of minerals like: iron, zinc and essential vitamins – some of which are barely found in plants, like Vitamin B12.

它含有所有必需氨基和我们的身体需要和许多矿物质，例如：铁，锌和必要的维生素，像维生素B12在植物中几乎找不到。

The nutrients themselves could come from conventional crops, but Dr Post also has plans to use algae, which grow faster than vascular plants, to provide the necessary amino acids, sugars and fats.

那些营养物质可以普通农作物中获取，但Post博士计划使用藻类，因为它们比那些维管植物长的要快，以此提供所需的氨基、糖类和脂肪。

I want to die every day, she says. After trying to end her life in 2003 by overdosing on a cocktail of drugs including Xanax and Percocet, Manning tried virtually every drug approved for bipolar disorder.

“我每天都想死，”她说。2003年，曼宁试图过量服用包括赞安诺和对乙酰氨基酚片剂在内的混合药物来结束自己的生命，之后她尝试了几乎所有批准用于治疗双相情感障碍的药物。

The work is practicable since they chemically modified these amino acids and peptides at their ends so they form a super-cooled liquid before decomposition, according to the study published on Saturday in the journal Science Advances.

根据周六发表在《科学展》杂志上的这项研究，这项工作是可行的，因为它们对这些氨基和肽的末端行了化学修饰，以便在分解前形成过冷的液体。

In this case, the amino acid cysteine (Cys) – found in milk products – was combined with the polyphenols CA and CGA – found in coffee – to make the adducts CA–Cys and CGA–Cys.

在这种情况下，奶制品中的氨基半胱氨（Cys）与咖啡中的CA和CGA结合，形成加合物 CA–Cys 和 CGA–Cys。

You can very well imagine a world in which living creatures are made up of 28 amino acids, but not the same ones as us.

你完全可以想象一个生物由28种氨基组成的世界，但这些氨基和我们不同。

But when you add or subtract one or two nucleotides, it essentially shifts all the remaining nucleotides, usually ends up in totally different amino acids being coded, and probably a dysfunctional protein.

但当你向核苷序列中增加或减少一个或两个核苷时，基本上会使全部剩余的核苷序列发生移位，最终会编码完全不一样的氨基序列，或者是一种功能失调的蛋白质。

For more than 50 years, scientists have tried to understand how proteins — the building blocks of biology — transform from simple chains of amino acids into precisely-folded 3D structures.

50 多年来，科学家们一直试图了解蛋白质——生物学的基石——是如何简单的氨基链转变为精确折叠的 3D 结构的。

Sodium, which is well-established as an essential part of our diet, and glutamate, a very common amino acid found in numerous plant and animal proteins.

一种是纳，它被公认为我们饮中不可或缺的一部分，另一种则是谷氨，一种非常常见的氨基存在于多种动植物蛋白质中。

And then the second thing to understand about serotonin, before we get into the practical tips, is that serotonin is made from an amino acid called tryptophan.

在介绍实用技巧之前，关于血清素需要了解的第二点是，它是由一种名为色氨的氨基合成的。
