- 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.

The most important ketone is acetone, a liquid with a sweetish odor.www.britannica.com/science/ketoneA ketone is an organic compound that has a carbon atom with a double bond to an oxygen atom (this is called carbonyl functional group). This carbon atom must also have single bonds to two other carbon atoms. A ketone can be produced by oxidating a secondary alcohol.simple.wikipedia.org/wiki/KetoneKetogenesis is the biochemical process through which organisms produce ketone bodies by breaking down fatty acids and ketogenic amino acids. The process supplies energy to certain organs, particularly the brain, heart and skeletal muscle, under specific scenarios including fasting, caloric restriction, sleep, or others.en.wikipedia.org/wiki/Ketogenesis

In organic chemistry, a ketone /ˈkiːtoʊn/ 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). The simplest ketone is acetone (where R and R' is methyl), with the formula … 展开
The word ketone is derived from Aketon, an old German word for acetone.

Ketone compounds have important physiological properties. They are found in several sugars and in compounds for medicinal use, including natural and synthetic steroid hormones. Molecules of the anti-inflammatory agent cortisone contain three ketone groups. - Only a small number of ketones are manufactured on a large scale in industry. They can be syn…
The most important ketone is acetone (CH3COCH3), a liquid with a sweetish odour. Acetone is one of the few organic compounds that is infinitely soluble in water (i.e., soluble in all proportions); it also dissolves many organic compounds. For this reason—and because of its low boiling poin…
