kenals, 4-hydroxy–2-alkenals, keto-alkenals, and alkanedial (dia-ldehydes) [3]. 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 other
The purpose of this study was to investigate the origin and function of the aldo-keto reductase (AKR) superfamily as enzymes involved in the detoxification of xenobiotics. We used the cyanobacteriu Advanced glycoxidation [1 – 3] end products (AGEs) and advanced lipoxidation end-products (ALEs) are widely studied as reporters of oxidative and glycoxidative damage [4 – 8]. The most common analytical methods for their quantitative determination are based on ELISA or … Most of the biological effects of RCS, mainly alpha,beta-unsaturated aldehydes, di-aldehydes, and keto-aldehydes, are due to their capacity to react with cellular constituents, forming advanced lipoxidation end-products (ALEs). Specific carbonyls, such as alpha-dicarbonyls, may be aldehydic or ketonic (or both) , and are very potent Maillard reaction intermediates, yielding advanced glycation end products (AGEs) as well as advanced lipoxidation end products (ALEs). the role of AKR1B3 in regulating advanced glycosylation end products and advanced lipoxidation end products; Genetic deficiency of Ar significantly ameliorated development of key endpoints linked with early diabetic nephropathy in vivo. a Y48F/H110F double mutant of AKR1B3 completely lost PGDS activity and showed only 2.9% of PGFS activity RCs react with proteins to form advanced lipoxidation end products (ALEs; [5,6], which are also known to cause oxidative cell dysfunction. Photosynthesis is the largest biological activity on earth involving anabolic sugar metabolism, and has the potential to generate sugar-derived and lipid-Abbreviations

Advanced lipoxidation end-products, such as MDA- and 4-HNE-protein adducts, can promote monocyte activation and vascular complications via induction of inflammatory pathways and networks . In monocytes, ALEs can lead to cellular dysfunction, adhesion to the endothelium, and transmigration into the subendothelial space, through several monocyte-macrophage inflammatory cytokines and chemokines.

Cardiovascular oxidative stress results in the oxidation of membrane lipids and the generation of reactive carbonyl species (RCS). The RCS react with proteins to form advanced lipoxidation products
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.
