| ketonimine dyes | Dye's in which the chromophore is ==C==NH connected to two benzene rings; alkylamino groups are added para to the methane carbon on both rings. The most important member for biological purposes is auramine O; an alternative formulation is as a diphenylmethane dye. (05 Mar 2000) |
|---|---|
| ketonization | Conversion into a ketone. (05 Mar 2000) |
| ketonuria | <biochemistry> The presence of ketone bodies in the urine, this is a symptom of diabetes mellitus. Origin: Gr. Ouron = urine (09 Oct 1997) |
| ketopantoic acid | Oxidised precursor of pantoic acid, intermediate on the synthetic pathway between alpha-ketoisovaleric acid and pantothenic acid. (05 Mar 2000) |
| ketopentose | A five-carbon sugar in which carbons 2, 3, or 4 make up part of a carbonyl group; e.g., ribulose. (05 Mar 2000) |
| ketoprofen | <chemical> 3-benzoyl-alpha-methylbenzeneacetic acid. An ibuprofen-type anti-inflammatory analgesic and antipyretic. It is used in the treatment of rheumatoid arthritis and osteoarthritis. Pharmacological action: non-steroidal anti-inflammatory agents, cyclooxygenase inhibitors. Chemical name: Benzeneacetic acid, 3-benzoyl-alpha-methyl- (12 Dec 1998) |
| ketorolac | A pyrrolo-pyrrole non-steroidal anti-inflammatory agent with antipyretic and analgesic properties; similar in actions to ibuprofen but substantially more potent and capable of relieving severe pain. Often used by injection. (05 Mar 2000) |
| ketose | <biochemistry> A simple sugar that has a ketoneas its carbonyl group. (09 Oct 1997) |
| ketose reductase | An oxidoreductase that catalyses the interconversion of d-sorbitol 6-phosphate and NAD+ to d-fructose 6-phosphate and NADH. A key step in fructose metabolism in the lens. Synonym: ketose reductase. (05 Mar 2000) |
| ketose-1-phosphate aldolase | Fructose bisphosphate aldolase. (05 Mar 2000) |
| ketosis | <biochemistry> Metabolic production of abnormal amounts of ketones. A consequence of diabetes melittus. (18 Nov 1997) |
| ketosis-prone diabetes | Type I or juvenile diabetes mellitus, in which inadequate treatment leads to development of ketoacidosis. (05 Mar 2000) |
| ketosis-resistant diabetes | Type II or adult onset diabetes mellitus, in which episodes of ketoacidosis rarely occur. (05 Mar 2000) |
| ketosteroid | <biochemistry> A steroid-like chemical which is a by-product of the breakdown of certain steroids. They are found in urine and measuring them can give a good indication of the level of androgen production in the body. The major ketosteroids are: androsterone, etiocholanone and oestrone. (09 Oct 1997) |
| ketosteroids | Steroid derivatives formed by oxidation of a methyl group on the side chain or a methylene group in the ring skeleton to form a ketone. (12 Dec 1998) |
