Lipid-derived reactive aldehydes link oxidative stress to cell

WebJun 15, 2000 · The structure of reactive aldehydes generated from lipid peroxidation, glycation, and amino acid oxidation. Glycation Glycation is a complex series of reactions between reducing sugars and amino groups of proteins, which leads to browning, fluorescence, and cross-linking of the proteins. Aldehydes participate in many reactions. From the industrial perspective, important reactions are (a) condensations, e.g., to prepare plasticizers and polyols, and (b) reduction to produce alcohols, especially "oxo-alcohols". From the biological perspective, the key reactions involve addition of nucleophiles to the formyl carbon in the formation of imines (oxidative deamination) and hemiacetals (structures of aldose sugars). incoming democratic house members
