Ketone, a source of energy in heart, brain. Ketones are produced in the body when fats, rather than glucose, are used to produce energy. This substance is an acid which can be harmful to the body if ketones are allowed to accumulate.
Glucose is usually used by cells for energy. But, when there's no insulin to help transport it out of the blood and into the cells, the body has an energy crisis and starts to break down body fat into ketones as an alternative fuel source. High levels of ketones in the body can be toxic. High blood glucose levels (over 250 mg/dl) are one sign that the body may have high levels of ketones circulating in the blood. This can progress to a serious complication called diabetic ketoacidosis.
