Reactive dicarbonyls
WebMar 21, 2024 · The 1,2-dicarbonyls, GO and MGO, are highly reactive byproducts of anaerobic glycolysis and lipid peroxidation. Specifically, the reactive 1,2-dicarbonyl glyoxal is formed endogenously through retroaldol condensation of glucose, the auto-oxidation of glycoaldehyde, and lipid peroxidation of polyunsaturated fatty acids through … WebMar 16, 2024 · Dicarbonyls react further to form irreversible products, the so–called AGEs. In addition to Maillard reactions, the polyol pathway, glycolysis, lipid peroxidation, and glucose autoxidation are involved in the formation of reactive dicarbonyls, such as methylglyoxal, glyoxal, and 3–deoxyglucosone.
