Ketone

A compound formed during the incomplete oxidation of fatty acids.

Acid chemical that builds up in the blood when the body burns fats instead of glucose.

A chemical compound that contains the carboxyl group.

A class of organic compounds produced by the body as an alternative fuel source once glucose is not readily available.

Chemical compounds containing a carbonyl group (C=0), with two alkyl groups attached to the same carbon; the simplest ketone is acetone (dimethylketone, (CH3)2-C=0).

A chemical compound produced when glucose is unavailable for use as energy, as in untreated diabetes, and fats are used instead, leading to ketosis.

Any of a group of organic chemicals derived by oxidation of alcohol and containing a carbon-oxygen group. Among the ketones are acetone and acetoacetic acid.

Ketones are organic compounds containing keto-groups, which in general are characterized by an oxygen molecule double bonded to carbon. In metabolism, ketones and ketoacids are produced from acetyl CoA. Acetone is a ketone and acetoacetate and beta-hydroxybutyrate are ketoacids produced in metabolism. Ketones can be utilized for energy by red blood cells and tissues of the central nervous system at times when glucose is unavailable. When ketone production increases to a rate greater than the rate of catabolism, a state of ketosis can occur, which is described in that entry.

Any member of a group of organic compounds consisting of a carbonyl group ( = CO) flanked by two alkyl groups. The ketones acetoacetic acid, acetone, and β-hydroxybutyrate (known as ketone (or acetone) bodies) are produced during the metabolism of fats.

Another name for acetone or dimethyl ketone. The term, ketone bodies, is applied to a group of substances closely allied to acetone, especially beta-hydroxybutyric acid and acetoacetic acid. These are produced in the body from imperfect oxidation of fats and protein foods, and are found in especially large amounts in severe cases of diabetes mellitus. Ketonuria is the term applied to the presence of these bodies in the urine, which can also occur after repeated vomiting.

A substance containing the carbonyl group (C — 0) attached to two carbon atoms. Acetone, CaH60, is an example of a simple ketone.

Substances produced in the body through a normal change fats undergo in the liver.

Ketones, a byproduct of an abnormal metabolic process involving fat, are generated under circumstances of inadequate carbohydrate intake and insulin deficiency within the body. This results in the breakdown of fats, rather than carbohydrates, to produce energy in a less efficient manner.

Toxic acidic substances generated by the body when fat is utilized as an energy source instead of glucose. The breakdown of fat occurs when there is an insufficient amount of insulin available to transport glucose into the cells of the body.

A variety of compounds linked to acetone, present in solvents like nail polish remover. Specific ketones form as a result of fat metabolism; when excessive quantities accumulate within the body, they trigger a condition known as ketosis.
