Descrição geral

Trans-2-Pentenal (pentenal) is an α,β-unsaturated aldehyde that increases [Ca2+] in cultured neonatal rat trigeminal ganglion (TG) neurons. The gas-phase reactions of NO3 radicals with pentenal in pure N2, using a relative rate technique, was studied.

The gas-phase reactions of NO(3) radicals with series of 1-alkenes, dienes, cycloalkenes, alkenols, and alkenals were studied in pure N(2) or 20% O(2)/80% N(2) bath gas at room temperature and atmospheric pressure using a relative rates technique. Rate coefficients were

Trans-2-Pentenal (pentenal), an alpha,beta-unsaturated aldehyde, induces increases in [Ca(2+)](i) in cultured neonatal rat trigeminal ganglion (TG) neurons. Since all pentenal-sensitive neurons responded to a specific TRPA1 agonist, allyl isothiocyanate (AITC) and neurons from TRPA1 knockouts failed to respond to pentenal

Thermal stressing of polyunsaturated fatty acid (PUFA)- rich culinary oils according to routine frying or cooking practices generates high levels of cytotoxic aldehydic products (predominantly trans-2-alkenals, trans,trans-alka-2,4-dienals, cis,trans-alka-2, 4-dienals, and n-alkanals), species arising from the fragmentation of conjugated hydroperoxydiene precursors.

Five alk-2-enals--pent-2-enal, hex-2-enal, hept-2-enal, oct-2-enal and non-2-enal--produced by lipid peroxidation were tested for mutagenic activity in V79 Chinese hamster cells. At concentrations ranging from 0.003 to 0.3 mM all 5 alk-2-enals induced a dose-dependent increase in the frequency of 6-thioguanine-resistant
