Reactive electrophile species
WebApr 2, 2024 · Oxylipins which contain an α,ß-unsaturated carbonyl structure are reactive electrophile species, called RES-oxylipins. The biological activities of RES-oxylipins show some overlap but mostly differ from the activities of non-RES-oxylipins such as jasmonic acid (JA) and its derivatives. WebDec 15, 2016 · Reactive electrophilic species (RES) are compounds containing α,β-unsaturated carbonyl or other electrophilic groups (Figure 1A) [].Because of their reactivity, they interact with macromolecules and affect cellular redox, mediated by redox cofactors like glutathione (GSH) and NAD(P)H [2,3].The results often involve cellular malfunction. α …

WebAbiotic and biotic stresses are often characterized by an induction of reactive electrophile species (RES) such as the jasmonate 12-oxo-phytodienoic acid (OPDA) or the structurally related phytoprostanes. Previously, RES oxylipins have been shown massively to induce heat-shock-response (HSR) genes including HSP101 chaperones. Moreover, WebJul 20, 2024 · A positively charged species such as a carbocation is electron-poor, and thus anything which donates electron density to the center of electron poverty will help to stabilize it. Alkyl groups, because of the electrons in their carbon-carbon and carbon-hydrogen bonds, are weak electron-donating groups, and will stabilize nearby carbocations.
WebApr 23, 2012 · Therefore, and because of the strong response of genes containing the 8-bp element to reactive electrophile species and oxylipins, the palindrome is designated as electrophile response element (ERE). The ERE is also required for the overexpression of GSTS1 in sor1 , supporting an interaction between SOR1 and the response to reactive ... WebOct 28, 2024 · Among the oxylipin carbonyls, those that have the α,β-unsaturated bond are grouped as reactive carbonyl species (RCS) (Mano, 2012; Mano et al., 2024a) or oxylipin …
These occur between alkenes and electrophiles, often halogens as in halogen addition reactions. Common reactions include use of bromine water to titrate against a sample to deduce the number of double bonds present. For example, ethene + bromine → 1,2-dibromoethane: C2H4 + Br2 → BrCH2CH2Br WebMay 1, 2003 · The results broaden the range of known biologic effects of reactive electrophile species to include the activation of a pathogenesis-related gene (HEL) and genes involved in metabolism....
