However, the Alzheimer's brain has no problem using ketones for energy.

然而，老年痴呆症患者大脑将酮作为其来源却没有任何问题。

Not only that, as he shows here, the Alzheimer's brain actually uptakes ketones better than controls.

不仅如此，正如他在这里所展示的与对照组相比，老年痴呆症患者大脑摄取酮的数要更多。

And it has been shown that ketones can provide up to 60% of the energy requirements for an adult brain.

研究表明，酮提供人大脑所的 60%。

You also have to know a little bit about ketosis because this is one of the goals of the coffee.

你还必须对酮症有一点了解，因为这是咖的目标之一（防弹咖减肥法会促进脂肪分解，产生大酮）。

Some research suggest that our bodies can adapt to other energy sources like ketone bodies and be less reliant on carbs.

一些研究表明，我们的身适应其他来源，如酮，减少对碳水化合物的依赖。

Very simply put, ketones are a source of energy naturally produced in the body from fat when dietary carbohydrate is restricted enough.

简而言之，当人碳水化合物摄入受限时酮——人内脂肪的代谢产物——便自然而然地成了大脑的新来源。

So during prolonged fasting or any kind of food deprivation situations, our body produces ketone bodies and these have been proposed to suppress appetite.

在长时间禁食或任何食物匮乏的情况下，我们的身会产生酮，这被认为是抑制食欲的。

These ketone bodies are important because they can be used by cells for energy, but they also increase the acidity of the blood, which is why it's called keto-acid-osis.

这些酮很重要，被细胞用来获取，但他们也会增加血液酸性，所才叫作酮症酸中毒。

As this 1986 paper reveals, " ketone bodies could account for as much as 25% of the neonate's basal energy requirements in the first several days of life."

正如这篇 1986 年的论文所揭示的，“新生儿最初几天的基本求中，酮占到 25%。”

Interestingly, both ketone bodies break down into acetone and escape as a gas by getting breathed out the lungs which gives a sweet fruity smell to a person's breath.

有趣的是，两种酮都会分解成丙酮，之后气形态随着肺部呼吸排出，会使患者的口气有一种水果似的甜味。

Beta hydroxybutyric acid on the other hand, even though it's still one of the ketone bodies, isn't technically a ketoacid since its ketone group has been reduced to a hydroxyl group.

而β-羟基丁酸虽说也是酮，但却不是酮酸，因为它的酮基团被还原成了羟基。

Because there is no more glucose and the fats are too large to cross the blood-brain barrier, your brain changes modes and begins to use ketone bodies for energy, which are short-chain derivatives of fatty acids.

因为没有更多的葡萄糖，脂肪又太大而不通过血脑屏障，你的大脑就会改变模式，开始使用酮作为，酮是脂肪酸的短链衍生物。

By analyzing the villi that provide contact with the mother's blood to the fetal membrane, Muneta deduced that the fetus must be living in an environment of elevated ketones from the start of pregnancy.

通过分析在母血液和胎膜之间起着纽带作用的绒毛，Muneta 推导出，在母受孕之，初胎儿便生活在一个酮水平较高的环境中。

After that happens, the liver turns the fatty acids into ketone bodies, like acetoacetic acid and beta hydroxybutyric acid; acetoacetic acid is a ketoacid because it has a ketone group and a carboxylic acid group.

此后，肝把脂肪酸转化成酮，比如乙酰乙酸、β-羟基丁酸；乙酰乙酸是一种酮酸，因为它有酮基团和羧酸基团。

Some of that acetone leaves your body when you exhale, and people with too many ketone bodies may even have a " fruity" smell to their breath from breathing out so much acetone.

当你呼气时， 一些丙酮会离开你的身，酮过多的人甚至会因为呼出过多的丙酮而闻到“水果味” 的气味。
