If this modification ends in mineral compounds like CO2, NH4+, or H2O, the biotransformation is called mineralisation.Trifluoroacetic anhydrideEnol etherPhenothiazineDeoxyguanosine diphosphateBenzopyrone: Benzopyrone may refer to either of two ketone derivatives of benzopyran which constitute the core skeleton of many flavonoid compounds:Carbon–fluorine bondPropyl benzoatePhenylpiperidine: Phenylpiperidine is a chemical compound with a phenyl moiety directly attached to piperidine. There are a variety of pharmacological effects associated some phenylpiperidines including morphine-like activity or other central nervous system effects.Combes quinoline synthesis: The Combes quinoline synthesis is a chemical reaction, which was first reported by Combes in 1888. It involves the condensation of unsubstituted anilines (1) with β-diketones (2) to form substituted quinolines (4) after an acid-catalyzed ring closure of an intermediate Schiff base (3).KavainSpin–lattice relaxation in the rotating frame: Spin–lattice relaxation in the rotating frame is the mechanism by which Mxy, the transverse component of the magnetization vector, exponentially decays towards its equilibrium value of zero, under the influence of a radio frequency (RF) field in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). It is characterized by the spin–lattice relaxation time constant in the rotating frame, T1ρ.Cyclohexanone monooxygenase: Cyclohexanone monooxygenase (, cyclohexanone 1,2-monooxygenase, cyclohexanone oxygenase, cyclohexanone:NADPH:oxygen oxidoreductase (6-hydroxylating, 1,2-lactonizing)) is an enzyme with system name cyclohexanone,NADPH:oxygen oxidoreductase (lactone-forming). This enzyme catalyses the following chemical reactionMesoionic: Mesoionic compounds are dipolar five membered heterocyclic compounds in which both the negative and the positive charges are delocalized. A completely uncharged structure cannot be written and mesoionic compounds cannot be represented satisfactorily by any one mesomeric structure.Burst kinetics: Burst kinetics is a form of enzyme kinetics that refers to an initial high velocity of enzymatic turnover when adding enzyme to substrate. This initial period of high velocity product formation is referred to as the "Burst Phase".ThiazolineAcid catalysis: In acid catalysis and base catalysis a chemical reaction is catalyzed by an acid or a base. The acid is the proton donor and the base is the proton acceptor.EzlopitantBenzo(c)thiopheneIndoleForskolinAllyl phenyl etherMicrosome: In cell biology, microsomes are vesicle-like artifacts re-formed from pieces of the endoplasmic reticulum (ER) when eukaryotic cells are broken-up in the laboratory; microsomes are not present in healthy, living cells.ImidazoleTable of standard reduction potentials for half-reactions important in biochemistry: The values below are standard reduction potentials for half-reactions measured at 25°C, 1 atmosphere and a pH of 7 in aqueous solution.Electrospray ionizationReaction coordinateArachidonic acidCalcium-activated potassium channel: Calcium-activated potassium channels are potassium channels gated by calcium, or are structurally or phylogenetically related to calcium gated channels. In humans they are divided into BK channels, IK channels, and SK channels based on their conductance (big, intermediate, and small conductance).Affinity label: Affinity labels are molecules similar in structure to a particular substrate for a specific enzyme and are considered to be a class of enzyme inhibitors. These molecules covalently modify active site residues in order to reveal the active site and thus elucidate its structure.TerpyridineClemizoleTosufloxacinCOX-3: COX-3 is an enzyme that is encoded by the PTGS1 (COX1) gene, but is not functional in humans. COX-3 is the third and most recently discovered cyclooxygenase (COX) isozyme, the others being COX-1 and COX-2.Specificity constant: In the field of biochemistry, the specificity constant (also called kinetic efficiency or k_{cat}/K_{M}), is a measure of how efficiently an enzyme converts substrates into products. A comparison of specificity constants can also be used as a measure of the preference of an enzyme for different substrates (i.PhenicarbazideTriphenyleneSulfone: A sulfone is a chemical compound containing a sulfonyl functional group attached to two carbon atoms. The central hexavalent sulfur atom is double bonded to each of two oxygen atoms and has a single bond to each of two carbon atoms, usually in two separate hydrocarbon substituents.Iocarmic acidKennel clubHigh-performance liquid chromatography: High-performance liquid chromatography (HPLC; formerly referred to as high-pressure liquid chromatography), is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material.Atomic mass: right |thumb|200px|Stylized [[lithium-7 atom: 3 protons, 4 neutrons, & 3 electrons (total electrons are ~1/4300th of the mass of the nucleus). It has a mass of 7.DNA binding site: DNA binding sites are a type of binding site found in DNA where other molecules may bind. DNA binding sites are distinct from other binding sites in that (1) they are part of a DNA sequence (e.Bismuth subsalicylateMasoprocolA. N. Hartley: Annie Norah Hartley (1902 – 1994), usually known simply as Norah Hartley, was a dog breeder and the first female board member of the Kennel Club.Torpedo ram: A torpedo ram is a type of torpedo boat combining a ram with torpedo tubes. Incorporating design elements from the cruiser and the monitor, it was intended to provide small and inexpensive weapon systems for coastal defence and other littoral combat.Proximity ligation assay: Proximity ligation assay (in situ PLA) is a technology that extends the capabilities of traditional immunoassays to include direct detection of proteins, protein interactions and modifications with high specificity and sensitivity. Protein targets can be readily detected and localized with single molecule resolution and objectively quantified in unmodified cells and tissues.
