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

We use nitrogen to clean the lacquer, and we use methyl ethyl ketone to keep the stylus clean.

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

然而，老年痴呆症患者将体作为其能量来源却没有任何题。

And when your body breaks down fats without much glucose around, it produces compounds called ketone bodies.

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，当人体碳水化合物入受限时体——人体内脂肪的代谢产物——便自然而然地成了能量的新来源。

This works for the time being, but ultimately only 75% of the brain's energy requirements can come from ketones. It still needs glucose!

这暂时会起到作用，但最终只能够满足所需能量的75%，它仍然需要葡萄糖！

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，如体，减少对碳水化合物的依赖。

Oxford University Emeritus Professor of Chemistry Gus Hancock says it is due to the build-up of chemicals called ketones in the patient's blood.

牛津学名誉教授化学加斯·汉考克表示这是由于被称为的化学物质在病人血液中累积所致。

Esters are just like a ketone mixed with an ether.
