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来源却没有问题。

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与对照组相比，老年痴呆症患者大脑摄取酮体数要更多。

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，因为这是咖啡目标之一（防弹咖啡减肥法会促进脂肪分解，产生大酮体）。

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

一研究表明，我们身体可以适应其他来源，如酮体，减少对碳水化合物依赖。

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 60%。

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，当人体碳水化合物摄入受限时酮体——人体内脂肪代谢产物——便自然而然地成了大脑新来源。

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

在长时间禁食或食物匮乏情况下，我们身体会产生酮体，这被认为是抑制食欲。

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 年论文所揭示，“新生儿最初几天基本需求中，酮体可占到 25%。”

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.

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

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，会使患者口气有一种水果似甜味。

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，因为它酮基团被还原成了羟基。

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绒毛，Muneta 推导出，在母体受孕之，初胎儿便生活在一个酮体水平较高环境中。

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体，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。

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.

因为没有更多葡萄糖，脂肪又太大而不通过血脑屏障，你大脑就会改变模式，开始使用酮体作为，酮体是脂肪酸短链衍生物。

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， 一丙酮会离开你身体，酮体过多人甚至可会因为呼出过多丙酮而闻到“水果味” 气味。
