Essential amino acids, or EAAs, are amino acids that our body needs but cannot produce on its own, and there are 9 of them: Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

基本基酸，简称 EAA，是我们身体需要但己产生的基酸，其中有 9 种：组酸，异亮酸，亮酸，赖酸，蛋酸，苯丙酸，苏酸，色酸和缬酸。

Aspartame is broken down to phenylalanine, aspartic acid, and methanol.

阿斯巴甜分解成苯丙酸、天冬酸和甲醇。

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食用苯丙酸和天冬酸，因为是几乎存在于所有蛋白质中的基酸。

And you'll see tryptophan, and tyrosine, and phenylalanine, and quinone gas, and lactic acid, cholesterol.

你会看到色酸、酪酸、苯丙酸、醌类气体、乳酸、胆固醇等成分。

For example, the essential amino acid, we'll just pick a brain one, tryptophan for serotonin production, or threonine for mucin production in the gut, which helps the gut lining, or, you know, take your pick, phenylalanine.

例如， 必需基酸，我们随便选一个， 色酸用于血清素的生成，或苏酸用于肠道黏液的生成，有助于保护肠壁，或是苯丙酸。

These are flagged up by lower than normal levels of things like leucine, glycerol and phenylalanine Your local environment breathing in polluted air has a marked impact on the profile of your metabolites.

些标志是由亮酸、甘油和苯丙酸等物质低于正常水平引起的。你所处的环境，比如吸入污染的空气，会对你的代谢物谱产生显着影响。
