Exempel på hur man kan använda KETONES i en mening

• Typically, the position of the carbonyl group is denoted by a number, but traditional nonsystematic names are still generally used for the most important ketones, for example acetone and benzophenone.
• In physiological ketosis, ketones in the blood are elevated above baseline levels, but the body's acid–base homeostasis is maintained.
• Acetals are formed from and convertible to aldehydes or ketones and have the same oxidation state at the central carbon, but have substantially different chemical stability and reactivity as compared to the analogous carbonyl compounds.
• It is common to several classes of organic compounds (such as aldehydes, ketones and carboxylic acids), as part of many larger functional groups.
• Rancidification is the process of complete or incomplete autoxidation or hydrolysis of fats and oils when exposed to air, light, moisture, or bacterial action, producing short-chain aldehydes, ketones and free fatty acids.
• Aldoses can be distinguished from ketoses, which have the carbonyl group away from the end of the molecule, and are therefore ketones.
• Oxybenzone or benzophenone-3 or BP-3 (trade names Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-3) is an organic compound belonging to the class of aromatic ketones known as benzophenones.
• Hydrazine, organohydrazines, and 1,1-diorganohydrazines react with aldehydes and ketones to give hydrazones.
• thumb When Brown started his own research, he observed the reactions of diborane with aldehydes, ketones, esters, and acid chlorides.
• Samples were identified to contain many components such as aliphatic and aromatic hydrocarbons, ketones, alcohols, acids and other poly functional components.
• Aldehydes are oxidized, giving a positive result, but ketones do not react, unless they are α-hydroxy ketones.
• The use of aldehyde in the name comes from its history: aldehydes are more reactive than ketones, so that the reaction was discovered first with them.
• An aldol condensation is a condensation reaction in organic chemistry in which two carbonyl moieties (of aldehydes or ketones) react to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), and this is then followed by dehydration to give a conjugated enone.
• Phosphonium ylides are used in the Wittig reaction, a method used to convert ketones and especially aldehydes to alkenes.
• While ketosis refers to any elevation of blood ketones, ketoacidosis is a specific pathologic condition that results in changes in blood pH and requires medical attention.
• They are basic nitrogenous compounds formed mainly by decarboxylation of amino acids or by amination and transamination of aldehydes and ketones.
• The law HG 767/2001 applies restrictions on where and how aurolac, which it uses as a generic term for a variety of substances containing ethers, ketones, acetates, as well as methanol and toluene, can be sold.
• Of such condensation products undoubtedly the most important are the hydrazones, which result from the interaction with aldehydes and ketones.
• LC-MS is particularly amenable to detecting hydrophobic molecules (lipids, fatty acids) and peptides while GC-MS is best for detecting small molecules (<500 Da) and highly volatile compounds (esters, amines, ketones, alkanes, thiols).
• Another important use in organic synthesis is for alkylation of ketones, which would otherwise form enolates if simple organolithium reagents were to be used.
