Product Description
Prostaglandin/jasmonate-like product of nonenzymatic lipid peroxidation. Occurs ubiquitously in healty plants and increases in response to oxidative stress. Could potentially be used as a marker of oxidative degradation of plant derived food. Powerful inducer of glutathione-S-transferase, jasmonic acid and other stress related responses. The role of phytoprostanes in human nutrition is not clarified yet, but they are associated with inhibition of dendritic cell interleukin-12 production and augmentation of TH2 cell polarization.
