Furthermore, the intensity of a specific C=C--H band at 808 [cm.sup.-1] decreased obviously after the epoxidation of EPDM, which demonstrated the conversion of C=C double chemical bond in EPDM to epoxy functional group in eEPDM [57].
Biosynthesis of maresin 1 in macrophages involves initial oxygenation of DHA with molecular oxygen, followed by epoxidation of the 14-hydroperoxy-intermediate that is subsequently converted to 13S,14S-epoxy-maresin.
Hence, they are chemically modified by the process of epoxidation. Epoxidation of fatty acids is a reaction of a carbon-carbon double bond with active oxygen, which results in the addition of an oxygen atom, converting the original double bond into a three membered epoxide (oxirane) ring (Figure 1).
This confirms that the cleavage of C = C bond is greater at lower temperatures and epoxidation participates more favorably against C = C cleavage to high temperatures [20, 21].
(5) Later studies revealed JHs to be a group of epoxy esters generated by homologation and epoxidation of methyl farnesoate.
But it's neither the carbon nanotubes nor the quartz wool that removes the metals, rather those involved in the research found that "the epoxidation via an oxidizing acid appears to be most responsible for adsorbing the metal," (http://news.rice.edu/2017/07/27/heavy-metals-in-water-meet-their-match/) according to the release .
Salen complexes of transition metals have been frequently used as catalysts in such diverse processes as oxygen and atom--transfer [11], enantioselective epoxidation [12], mediating organic redox reactions [13] and recently as ionophores in ion--selective studies [14].
Specific dehydrogenation of 3-methylindole and epoxidation of naphthalene by recombinant human CYP2F1 expressed in lymphoblastoid cells.
Minor reactions included isopropyl chain hydroxylation (A8, A16, A17), pentyl carboxylation (A10), oxidative deamination of the carboxamide group (A18, A19), dehydrogenation (A16, A19), A-depentylation (A4), and epoxidation followed by hydrolysis (A7).

The controlled partial epoxidation of NR to form epoxidized NR (ENR) is one of the important methods that introduce a new reactive group into the NR backbone, leading to the new and useful properties.
For instance, sesquiterpene [alpha]-farnesene is stress induced [31] and can be easily degraded due to photochemical allylic oxidation, hydroxylation, and epoxidation [32].
