Ketone Bodies

Ketone bodies (pronunciation: /ˈkiːtoʊn ˈbɒdiz/) are three water-soluble molecules (acetoacetate, beta-hydroxybutyrate, and their spontaneous breakdown product, acetone) that are produced by the liver from fatty acids during periods of low food intake (fasting), carbohydrate restrictive diets, starvation, prolonged intense exercise, alcoholism or in untreated (or inadequately treated) type 1 diabetes mellitus.

Etymology

The term "ketone bodies" is derived from the fact that they are intermediate products of fat metabolism. The term "ketone" comes from the German word "keton", which was derived from the word "Aketon", meaning acetone.
