Exempel på hur man kan använda KETONE i en mening

• According to the rules of IUPAC nomenclature, ketone names are derived by changing the suffix -ane of the parent alkane to -anone.
• β-Ketoglutaric acid (also termed 3-oxoglutaric acid and acetonedicarboxlic acid) and its conjugate base, β-Ketoglutarate, differ from α-ketoglutaric acid and α-ketoglutarate by the position of their ketone, i.
• Ketosis is a metabolic state characterized by elevated levels of ketone bodies in the blood or urine.
• In humans and many other animals, they serve to break down alcohols that are otherwise toxic, and they also participate in the generation of useful aldehyde, ketone, or alcohol groups during the biosynthesis of various metabolites.
• Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications.
• A classic laboratory method for the preparation of anthracene is by cyclodehydration of o-methyl- or o-methylene-substituted diarylketones in the so-called Elbs reaction, for example from o-tolyl phenyl ketone.
• Ketogenesis is the biochemical process through which organisms produce ketone bodies by breaking down fatty acids and ketogenic amino acids.
• The name is derived from that of quinic acid (with the suffix "-one" indicating a ketone), since it is one of the compounds obtained upon oxidation of quinic acid.
• Here, with a group of his doctoral students, he proved the structure of the compounds muscone and civetone, macrocyclic ketone scents derived from the musk deer (Moschus moschiferus) and the civet cat (Viverra civetta).
• Classically, the Grignard reaction refers to the reaction between a ketone or aldehyde group with a Grignard reagent to form a primary or tertiary alcohol.
• An enamine is an unsaturated compound derived by the condensation of an aldehyde or ketone with a secondary amine.
• In organic chemistry, an aldol is a structure consisting of a hydroxy group (-OH) two carbons away from either an aldehyde or a ketone.
• In its usual form, it involves the nucleophilic addition of a ketone enolate to an aldehyde to form a β-hydroxy ketone, or aldol (aldehyde + alcohol), a structural unit found in many naturally occurring molecules and pharmaceuticals.
• In an aldose, C1 is the carbon of the aldehyde group; in a ketose, C1 is the carbon closest to the ketone group, which is typically found at C2.
• Ketoacidosis is a metabolic state caused by uncontrolled production of ketone bodies that cause a metabolic acidosis.
• It also finds use for the synthesis of hydantoins, which can be useful synthetic intermediates, when reacted with a carbonyl compound such as an aldehyde or ketone in the presence of ammonium carbonate.
• Several pathways exist for the halogenation of organic compounds, including free radical halogenation, ketone halogenation, electrophilic halogenation, and halogen addition reaction.
• It is derived from the reaction of methyl ethyl ketone and hydrogen peroxide under acidic conditions.
• An elevated level of ketone bodies in the blood (a state called ketosis) eventually lowers the frequency of epileptic seizures.
• Oxidation by a cytochrome P450 in the CYP71D subfamily creates a dienol intermediate, which is then converted into a ketone by short-chain dehydrogenase.
