ketone bodies
Liver-made energy molecules
Ketone bodies are compounds produced by the liver when the body breaks down fat for energy instead of glucose.
The three ketone bodies—acetoacetate, beta-hydroxybutyrate, and acetone—accumulate during fasting, low-carbohydrate diets, or uncontrolled diabetes.
Her ketone bodies were elevated after three days of fasting.
Dangerously high levels cause ketoacidosis, a medical emergency.
