Data on lipid hydroperoxide isomers and lipoxygenase specificity in potato fruit juice

This study aimed to quantify the levels and relative proportions of 9- and 13-hydroperoxyoctadecadienoic acid (HPODE) in the fruit juice of five industrial potato cultivars (Kuras, Saprodi, Cultivar X, Ydun, and Stratos), and to assess whether significant differences exist among them.

The dataset consists of two sheets. The “Intensity” sheet contains the raw intensity data for 9-HPODE and 13-HPODE measured in three biological replicates for each cultivar. In addition, the total intensity has been calculated, and the mean and standard deviation (STD) of the three replicates are provided. The “Percentage” sheet presents the relative levels of 9- and 13-HPODE expressed as a percentage of the total intensity.

The results indicate that the potato cultivars have similar total levels of lipid hydroperoxides but differ in the ratio of 9- to 13-HPODE. Overall, the 9-HPODE isomer predominates, suggesting a greater contribution of 9-lipoxygenase activity and oxidation at the C9 position. However, variations in the isomer ratio among cultivars point to differences in the relative activity of lipid oxidation pathways.

Further details on data acquisition are provided in the “Steps to reproduce” section.
