Ketones, or ketone bodies, are acids your body makes when it’s using fat instead of glucose for energy. Your body gets most of its energy from glucose, a sugar that mainly comes from carbohydrates in your diet.

Dec 17, 2024 · Ketones, also known as “ketone bodies,” are energy molecules created by the liver from the breakdown of fats. Your body makes ketones when you don’t have access to carbs or enough glucose stores (glycogen), such as when on a ketogenic diet.

Nov 28, 2023 · What Is a Ketone Test? A ketone test can warn you of a serious diabetes complication called diabetic ketoacidosis, or DKA. An elevated level of this substance in your blood can mean that you...

May 26, 2022 · Ketones are chemical substances that develop as the body breaks down fat. A certain level of ketones in the body can be normal. However, having high levels of ketones may cause ketoacidosis, which is a serious complication that can have further effects on health.

Oct 10, 2022 · Ketones are chemical structures produced from the breakdown of fatty acids in the liver when the body cannot use glucose (or sugar) for energy. Instead of getting energy from carbohydrates or glucose, the body relies on energy from fat.

In organic chemistry, a ketone / ˈ k iː t oʊ n / is an organic compound with the structure R−C(=O)−R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group −C(=O)− (a carbon-oxygen double bond C=O).

Mar 8, 2025 · ketone, any of a class of organic compounds characterized by the presence of a carbonyl group in which the carbon atom is covalently bonded to an oxygen atom. The remaining two bonds are to other carbon atoms or hydrocarbon radicals (R): Ketone compounds have important physiological properties.

Ketones are a type of chemical that your liver produces when it breaks down fats. Your body uses ketones for energy typically during fasting, long periods of exercise, or when you don’t have as many carbohydrates. You can have low levels of ketones in your blood without it being a problem.

Nov 13, 2024 · Ketones are chemicals produced by your liver cells when your body breaks down fat for energy. Urine, blood, and breath tests can determine ketone levels.

Aug 14, 2022 · Ketones are bodies that live in the body which act as water-soluble molecules. The ketones bodies are produced by the liver from fatty acids. These fatty acids are a consequence of low calorie intake, diets that restrict carbohydrates, intense exercise, starvation and most commonly, type 1 diabetes.
