酮体:Chemicals that the body makes when there is not enoughinsulinin the blood and it must break down fat instead of the sugar glucose for energy. Theketone bodies-- acetone, acetoacetate, and beta-hydroxybutyrate -- are toxic acidic chemicals. They build up in the blood and then spill over into the urine. The body can also rid itself of acetone through thelungs. This gives the breath a fruity odor.
The presence of ketone bodies in the blood is termed ketosis and the presence of ketone bodies in the urine is calledketonuria.
