What structure represents ketones?
In chemistry, a ketone /ˈkiːtoʊn/ is a functional group with the structure R2C=O, where R can be a variety of carbon-containing substituents. Ketones contain a carbonyl group (a carbon-oxygen double bond).
In a ketone, the carbonyl group is bonded to two carbon atoms: As text, an aldehyde group is represented as –CHO; a ketone is represented as –C(O)– or –CO–. In both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigonal planar; the carbon atom exhibits sp2 hybridization.
Some Common Ketones. In terms of scale, the most important ketones are acetone, methylethyl ketone, and cyclohexanone. They are also common in biochemistry, but less so than in organic chemistry in general. Dimethyl ketone, CH3COCH3, commonly called acetone, is the simplest ketone.

| Pentanal (valeraldehyde) | 2-Methylpropanal |
Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde.
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.
An aldehyde as well as a ketone can be represented by the same molecular formula, say C3H6O.
Ketohexose: A monosaccharide having both a ketone (a ketose) and six carbons (a hexose). the most important example is} fructose.
The functional group of a ketone is a carbonyl group bonded to two carbon atoms.
Ketones are always present in the blood and their levels increase during fasting and prolonged exercise. They are also found in the blood of neonates and pregnant women. Diabetes is the most common pathological cause of elevated blood ketones.
Is CH3COCH3 a ketone?
Acetone, an organic compound, is chemically described as CH3COCH3, and can also be referred to as 2-propanone. Acetone is a hydrocarbon derivative, more specifically a ketone in its simplest form because of its particular functional group.

Ketones are chemical substances produced when the body burns fat as an energy source. They are similar in chemical composition to isopropyl alcohol. This is the type of alcohol found in solvents such as acetone.
Aldehydes and Ketones are often called as methanoyl or formyl group. The carbon atom of this group has 2 remaining bonds that might be occupied by aryl or alkyl or substituents. If neither of these substituents is hydrogen, the compound is a Ketone. If at least one is hydrogen, the compound is an Aldehyde.
It is widely known as acetone, a unique name unrelated to other common names for ketones. Generally, the common names of ketones consist of the names of the groups attached to the carbonyl group, followed by the word ketone. (Note the similarity to the naming of ethers.)
The first member of the ketone family is acetone or propanone. Molecular formula is C3H6O or CH3-CO-CH3 or (CH3)2CO.
No, it is not carbohydrates, fats, or even protein. We call them ketones or ketone bodies (more on the difference between the two later). To your body, however, ketones are nothing new. In fact, your heart and renal cortex (the part of the kidney where ultrafiltration occurs) are using ketones as fuel right now.
When in ketosis, the body begins to burn stored fats for energy, and this results in the build-up of acids, known as ketones, in your blood. A person following the keto diet aims to burn unwanted fat by actually pushing the body to rely on fat, not carbohydrates, for energy.
Fructose, Xylulose, and ribulose are the three main examples of ketose sugar.
Which of the following is not a keto sugar?
Which the following regarding to examples of Keto sugar is not correctly? Which the following regarding to examples of Keto sugar is not correctly? (d) Dihydroxy acetose.
2) Which of the following is the simplest form of carbohydrates? Sol: (b) Aldehyde and Ketone groups.
Which of the following best describes the term ketone? A ketone is an organic compound containing a carbonyl group attached to two carbons.
Alcohols contain the hydroxyl functional group and can be primary, secondary, or tertiary. Ethers are compounds with an oxygen atom bonded to two alkyl groups. Aldehydes and ketones contain the carbonyl functional group.
Which of the following is the distinguishing characteristic between aldehydes and ketones? Ketones contain a carbonyl group between two carbons, while the carbonyl group in an aldehyde must be attached to a hydrogen.
