Exempel på hur man kan använda EPOXIDE i en mening

• Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups.
• It is a highly oxidized tetranortriterpenoid which boasts a plethora of oxygen-bearing functional groups, including an enol ether, acetal, hemiacetal, tetra-substituted epoxide and a variety of carboxylic esters.
• A compound containing the epoxide functional group can be called an epoxy, epoxide, oxirane, and ethoxyline.
• Among the first introduced to chemistry students are Markovnikov's rule for the addition of protic acids to alkenes, and the Fürst-Plattner rule for the addition of nucleophiles to derivatives of cyclohexene, especially epoxide derivatives.
• Xanthophylls are a subset of carotenoids, identified by the fact that they are oxygenated either as hydroxyl groups or as epoxide bridges.
• Epoxide hydrolases (EHs), also known as epoxide hydratases, are enzymes that metabolize compounds that contain an epoxide residue; they convert this residue to two hydroxyl residues through an epoxide hydrolysis reaction to form diol products.
• As the antibiotic is broken down in the body, it releases free NMTT, which can cause hypoprothrombinemia (likely due to inhibition of the enzyme vitamin K epoxide reductase) and a reaction with ethanol similar to that produced by disulfiram (Antabuse), due to inhibition of aldehyde dehydrogenase.
• Halohydrins may also be prepared from the reaction of an epoxide with a hydrohalic acid, or a metal halide.
• Related Lewis acid-promoted reactions include as epoxide ring openings and decomplexation of dienes from iron carbonyls.
• Beside the CYP family NNK can also be activated by metabolic genes, like myeloperoxidase (MPO) and epoxide hydrolase (EPHX1).
• In the case of neosporol, a Prilezhaev reaction with trifluoroperacetic acid is used to convert a suitable allyl alcohol precursor to an epoxide, which then undergoes a ring-expansion reaction with a proximate carbonyl functional group to form the dioxolane ring.
• Following the lead of Dachlauer and Jackel, contemporary routes to episulfides utilize a two-step method, converting an olefin to an epoxide followed by thiation using thiocyanate or thiourea.
• Based on its 1,3-disubstituted urea structure, sorafenib is also a potent soluble epoxide hydrolase inhibitor and this activity likely reduces the severity of its adverse effects.
• The reaction is mediated by a D-fructose derived catalyst, which produces the (R,R) enantiomer of the resulting epoxide.
• Upon oxidation with permanganate, cycloglycols will dehydrate to yield an aldehyde via an epoxide intermediate.
• EDP and EEQ metabolites are short-lived, being inactivated within seconds or minutes of formation by epoxide hydrolases, particularly soluble epoxide hydrolase, and therefore act locally.
• EETs are generally short-lived, being rapidly converted from epoxides to less active or inactive dihydroxy-eicosatrienoic acids (diHETrEs) by a widely distributed cellular enzyme, soluble epoxide hydrolase (sEH), also termed epoxide hydrolase 2.
• Glycidic esters can also be obtained via nucleophilic epoxidation of an α,β-unsaturated ester, but that approach requires synthesis of the alkene substrate first whereas the Darzens condensation allows formation of the carbon–carbon connectivity and epoxide ring in a single reaction.
• In particular, CYP2C9 metabolizes arachidonic acid to the following eicosatrienoic acid epoxide (EETs) stereoisomer sets: 5R,6S-epoxy-8Z,11Z,14Z-eicosatetraenoic and 5S,6R-epoxy-8Z,11Z,14Z-eicosatetraenoic acids; 11R,12S-epoxy-8Z,11Z,14Z-eicosatetraenoic and 11S,12R-epoxy-5Z,8Z,14Z-eicosatetraenoic acids; and 14R,15S-epoxy-5Z,8Z,11Z-eicosatetraenoic and 14S,15R-epoxy-5Z,8Z,11Z-eicosatetraenoic acids.
• One analysis of 200 candidate genes of Siraitia grosvenorii revealed five enzyme families involved in the synthesis of mogroside V: squalene epoxidases, triterpenoid synthases, epoxide hydrolases, cytochrome P450s, and UDP-glucosyltransferases.
