ketone
(redirected from ketonic)

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
ketone /ke·tone/ (ke´tōn) any of a class of organic compounds containing the carbonyl group, CdbondO, whose carbon atom is joined to two other carbon atoms, i.e., with the carbonyl group occurring within the carbon chain.
Ketone.

ke·tone (ktn)
n.
Any of a class of organic compounds having a carbonyl group linked to a carbon atom in each of two hydrocarbon radicals.

ketone
[kē′tōn]
Etymology: Fr, acetone
an organic chemical compound characterized by having in its structure a carbonyl, or keto, group, ═CO, attached to two alkyl groups. It is produced by oxidation of secondary alcohols.

ketone [ke´tōn]
any compound containing the carbonyl group, C=O, and having hydrocarbon groups attached to the carbonyl carbon, i.e., the carbonyl group is within a chain of carbon atoms.
ketone bodies the substances acetone, acetoacetic acid, and β-hydroxybutyric acid; except for acetone (which may arise spontaneously from acetoacetic acid), they are normal metabolic products of lipid and pyruvate within the liver, and are oxidized by muscles. Excessive production leads to urinary excretion of these bodies, as in diabetes mellitus; see also ketosis. Called also acetone bodies.

ketone,
n compound that contains a carbonyl group attached to a carbon in a chain. Used as analgesics, antiinflammatories, expectorants, and stimulants.

ketone bodies
the substances acetone, acetoacetic acid and β-hydroxybutyric acid; except for acetone (which may arise spontaneously from acetoacetic acid), they are normal metabolic products usually derived from excess acetyl CoA from fatty acids within the liver, and are oxidized by the extrahepatic tissues; excessive production leads to urinary excretion of these bodies, as in diabetes mellitus. Called also acetone bodies. See also ketosis, acetonemia, pregnancy toxemia.

These authors also observed that the intensity of this peak increases with the number of processing cycles and this was attributed to the formation of ketonic group.
Astaxanthin is a member of the oxygenated xanthophylls, and its high level of antioxidant power likely comes from the ketonic and hydroxyl functional groups of the ionone ring structure.
