Ketone bodies are three water-soluble compounds that are produced as by-products when fatty acids are broken down for energy in the liver. Two of the three are used as a source of energy in the heart and brain while the third is a waste product excreted from the body. In the brain, they are a vital source of energy during fasting. Although termed "bodies", they are dissolved substances, not particles.
The three endogenous ketone bodies are acetone, acetoacetic acid, and beta-hydroxybutyric acid, although beta-hydroxybutyric acid is not technically a ketone but a carboxylic acid. Other ketone bodies such as beta-ketopentanoate and beta-hydroxypentanoate may be created as a result of the metabolism of synthetic triglycerides such as triheptanoin.

Famous quotes containing the word bodies:
“We thought it would be worth the while to read the epitaphs where so many were lost at sea; however, as not only their lives, but commonly their bodies also, were lost or not identified, there were fewer epitaphs of this sort than we expected, though there were not a few. Their graveyard is the ocean.”
—Henry David Thoreau (18171862)
