Disease relevance of pentanal

• Soybean milk, which serves as a base for a variety of beverages, contains raffinose, stachyose, pentanal and n-hexanal; the former two may be responsible for flatulence after fermentation, whilst the latter two for a beany flavour [1].

High impact information on pentanal

• Thus, cytokine-induced increases in malondialdehyde (MDA; at 4 h) and 4-HNE (at 8 h) preceded islet cell destruction (at 16 h), and the addition of 4-HNE, hexanal, MDA, and pentanal (1-200 microM) to th islets, but not other aldehydes at similar concentrations, produced dose-dependent destruction of islet beta-cells [2].
• Supercritical fluid extraction (SFE) of daphnoretin, 7-methoxy-daphnoretin and 1,5-diphenyl-1- pentanone from Stellera chamaejasme L. was performed [3].
• A headspace gas chromatographic method to determine propanal, pentanal and hexanal as the main volatiles present in the headspace of powder infant formula oxidation is described as a rapid indication of oxidative status [4].
• The in vitro activity of the enzyme was inhibited by ethacryanic acid, trans-2-hexenal, crotonaldehyde, and pentanal [5].
• Evaluation of n-valeraldehyde modified chitosan as a matrix for hydrophobic interaction chromatography [6].

Biological context of pentanal

• Vapors of known concentrations around the threshold limit values time-weighted average of n-valeraldehyde and specific relative humidities (RHs) were generated by syringe pumps in a dynamic generation system. n-Valeraldehyde vapors in gas bags were also generated [7].
• The n-valeraldehyde modified Chitosan (pentyl-Chitosan CL) was prepared by Schiff-base formation and hydrogenation [6].

Anatomical context of pentanal

• In rat hepatocytes, propanol (10-100 mM), butanal (10-100 mM), pentanal (3-30 mM) and hexanal (3-30 mM) induced a modest but significant and dose-dependent increase of net nuclear grain counts, while in human hepatocytes this effect was not detected [8].

Associations of pentanal with other chemical compounds

• Hexanal, pentanal, (E)-2-hexenal, and heptanal levels were negatively correlated with the addition of turmeric in dill pickles with oxygen injected into the jar, indicating that the curcumin present in turmeric is an effective antioxidant in this product [9].
• Further tandem mass spectrometry analysis of one of the modified peptides (Pro-Thr-His-Ile-Lys-Trp-Gly-Asp) strongly suggested binding of one pentanal molecule to the amino terminal proline and three pentanal molecules bound to the lysine residue [10].
• The effect of antioxidants, added in a single initial dose or in weekly additions to extended shelf life milk, was evaluated over 6 wk of lighted storage at 4 degrees C. Light-induced oxidation was measured by determining pentanal, hexanal, heptanal, and 1-octen-3-ol contents [11].
