WebLipid dicarbonyls are secondary products that have two closely spaced reactive groups, making them extremely reactive with proteins and other macromolecules and therefore highly damaging. Important lipid dicarbonyls include IsoLGs (also called isoketals), 4-oxo-nonenal (ONE), and malondialdehyde (MDA) ( Figure 1 ). WebWe examined whether scavenging reactive dicarbonyls with 5′-O-pentyl-pyridoxamine (PPM) protects against the development of IR and atherosclerosis in Ldlr−/− mice. Methods: Male or female Ldlr−/− mice were fed a western diet (WD) for 16 weeks and treated with PPM versus vehicle alone. Plaque extent, dicarbonyl-lysyl adducts ...
