Description

General description

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.

In vivo absorption, metabolism, and urinary excretion of alpha,beta-unsaturated aldehydes in experimental animals. Relevance to the development of cardiovascular diseases by the dietary ingestion of thermally stressed polyunsaturate-rich culinary oils.

M Grootveld et al.

The Journal of clinical investigation, 101(6), 1210-1218 (1998-04-29)

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.

Multiple cation channels mediate increases in intracellular calcium induced by the volatile irritant, trans-2-pentenal in rat trigeminal neurons.

Takashi Inoue et al.

Cellular and molecular neurobiology, 30(1), 35-41 (2009-07-02)

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

Kinetics studies of the gas-phase reactions of NO3 radicals with series of 1-alkenes, dienes, cycloalkenes, alkenols, and alkenals.

Zhijun Zhao et al.

The journal of physical chemistry. A, 115(44), 12161-12172 (2011-10-15)

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
