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体作为其能量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，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体的数量要更多。

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

研究表明，酮体可以提供人体大脑所需能量的 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，生大量酮体）。

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，我们的身体可以适应其他能量来源，酮体，减少对碳水化合的依赖。

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，当人体碳水化合摄入受限时酮体——人体内脂肪的代谢——自然而然地成了大脑能量的新来源。

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匮乏的情况下，我们的身体会生酮体，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.

这些酮体很重要，可被细胞用来获取能量，但他们也会增加血液酸性，所以才叫作酮症酸中毒。

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."

这篇 1986 年的论文所揭示的，“新生儿最初几天的基本能量需求中，酮体可能占到 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，两种酮体都会分解成丙酮，之后以气体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体，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，脂肪又太大而不能通过血脑屏障，你的大脑就会改变模式，开始使用酮体作为能量，酮体是脂肪酸的短链衍生。

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.

通过分析在母体血液和胎膜之间起着纽带作用的绒毛，Muneta 推导出，在母体受孕之，初胎儿生活在一个酮体水平较高的环境中。

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.

后，肝把脂肪酸转化成酮体，比乙酰乙酸、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体，酮体过多的人甚至可能会因为呼出过多的丙酮而闻到“水果味” 的气味。
