Sigma-Aldrich offers abstracts and full-text articles by [Rosemary E McDowell, Mary K McGahon, Josy Augustine, Mei Chen, J Graham McGeown, Tim M Curtis]. Similarly, advanced glycation end products (AGEs) are formed by reaction of carbonyl substances such as carbohydrates and proteins . ROS and RNS can also damage nucleic acids, generating pyrimidine and purine base adducts. 8-oxo-2 - deoxyguanosine is thought to be the most representative product of oxidative modifications of DNA and can correlate with the level of oxidative DNA damage in the Az átmeneti, illetve a tartós hyperglykaemia következménye a sejten belüli reaktív oxigéngyökök mellett a reaktív aldehidek The Amadori products undergo dehydration and rearrangements and develop a cross-link between adjacent proteins, giving rise to protein aggregation or advanced glycation end products (AGEs). A number of studies have shown that glycation induces the formation of the β-sheet structure in β-amyloid protein, α-synuclein, transthyretin (TTR), copper-zinc superoxide dismutase 1 (Cu, Zn-SOD-1), and peroxidation (lipoxidation) reactions in vitro, and we show that it traps reactive intermediates formed during lipid peroxidation.

The most reactive and commonly studied are mal-ondialdehyde (MDA), acrolein (ACR), 4-hydroxyhexanal (4-HHE) and 4-hydroxynonenal (HNE), which also reflects the fact that these products are produced at higher levels than many other01.05.2002
Advanced glycation end products naturally form in our bodies from the chemical reaction of sugars with proteins. How can you limit your AGE intake?

3. Pathophysiological relevance of lipoxidation adducts. Evidence for occurrence of lipoxidation products in vivo has expanded greatly in the last 10 years, as more sensitive and specific methodology has been developed, and now there are many examples of lipoxidized proteins in both healthy and diseased tissues. Much of the work has focused on HNE, but there are also many examples of adducts
Advanced Lipoxidation End-products (ALEs) are modified proteins that can act as pathogenic factors in several chronic diseases. Several molecular mechanisms have so far been considered to explain the damaging action of ALEs and among these a pathway involving the receptor for advanced glycation end products (RAGE) should be considered.
