peroxy वाक्य

उदाहरण वाक्य

1. ""'meta "-Chloroperoxybenzoic acid "'( "'mCPBA "') is a peroxycarboxylic acid used widely as an oxidant in organic synthesis . mCPBA is often preferred to other peroxy acids because of its relative ease of handling.
2. In PUFAs that do not have a third carbon-carbon double bound between their ?-13 and ?-12 carbons, human ALOX15 forms ?-6 peroxy intermediates; in PUFAs that do have this third double bound, human ALOX15 makes the ?-6 peroxy intermediate but also small amounts of the ?-9 peroxy intermediate.
3. In PUFAs that do not have a third carbon-carbon double bound between their ?-13 and ?-12 carbons, human ALOX15 forms ?-6 peroxy intermediates; in PUFAs that do have this third double bound, human ALOX15 makes the ?-6 peroxy intermediate but also small amounts of the ?-9 peroxy intermediate.

5. The high reactivity of trifluoroperacetic acid relative to other peroxy acids allows it to successfully oxidize relatively electron-poor alkenes such as 1-hexene and vicinal hydroxy trifluoroacetate structure instead of an epoxide, which can be converted to the diol by treatment with acidic methanol, such as in the following conversion of 1-dodecene to 1, 2-dodecanediol.
6. The propagation of thermal degradation can involve a variety of reactions and one of these is where the free radical ( R " ) reacts with an oxygen ( O 2 ) molecule to form a peroxy radical ( ROO " ) which can then remove a hydrogen atom from another polymer chain to form a hydroperoxide ( ROOH ) and so regenerate the free radical ( R " ).
7. Matrix defects can also be present; oxygen vacancies, silicon vacancies ( usually compensated by 4 hydrogens or 3 hydrogens and a hole ), peroxy groups, etc . Some of the defects produce localized levels in the forbidden band, serving as charge traps; Al ( III ) and B ( III ) typically serve as hole traps while electron vacancies, titanium, germanium, and phosphorus atoms serve as electron traps.
8. They commonly catalyze the attachment of molecular oxygen as a peroxy residue to polyunsaturated fatty acids ( PUFA ) that contain two carbon-carbon double bonds that for the human ALOX15 are located between carbons 10 and 9 and 7 and 6 as numbered counting backward from the last or omega ( i . e . ? ) carbon at the methyl end of the PUFA ( these carbons are also termed ?-10 and ?-9 and ?-7 and ?-6 ).
