As model lipid-derived carbonyl compounds, an alkenal (2-pentenal), an alkadienal (2,4-heptadienal), an oxoalkenal (4-oxo-2-hexenal), and two epoxyalkenals (4,5-epoxy-2-heptenal and 4,5-epoxy-2-decenal) were employed. 2-Pentanal and 2,4-decadienal were purchased from Sigma-Aldrich (St. Louis, MO), 4-oxo-2-hexenal was prepared from 2-ethylfuran by ring opening (Zamora, Alcon, & Hidalgo, 2013) , and 4,5-epoxy-2heptenal and 4,5-epoxy-2-decenal were synthetized from their corresponding alkadienals (2,4-heptadienal and 2,4-decadienal) by epoxidation with 3chloroperoxybenzoic acid (Zamora, Gallardo, & Hidalgo, 2006) .
As phenolic compounds a wide array of model compounds as well as flavonoids were employed. They are collected in Fig. 1. They included simple m-diphenols: resorcinol (1), 2-methylresorcinol (2), 2,5-dimethylresorcinol (3), and 2,6dihydroxybenzoic acid (4); other simple phenols: 4-methylcatechol (5), hydroquinone (6), and sesamol (7); flavonols: quercetin (8), myricetin (9), and morin (10); flavan-3ols: catechin (11) and epicatechin (12); and stilbenoids: resveratrol (13). All these compounds, as well as all other chemicals employed in these studies, were purchased from Sigma-Aldrich (St. Louis, MO), Fluka (Buchs, Switzerland), or Merck (Darmstadt, Germany) and were of the highest available grade.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
