Biological membranes play key roles in cell life, acting as permeability barriers and constituting privileged sites of communication between the inside and the outside of cells [1
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 (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.
A review from 2000 summarized additional identifications of different advanced lipoxidation end-products found in atherosclerotic lesions, including MDA-lysine , HNE-lysine , , and levuglandin E2 , which were analysed by both immunohistochemical and chemical techniques . lipid peroxidation products is remarkable. We will focus in this contribution on lipid peroxidation products with α,β-unsaturated keto/aldehyde moiety as reactivity site and engage in covalent interaction with proteins to exert their biological roles. Examples of such lipoxidation-derived electrophiles are compiled in … 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 …
Jun 30, 2011 · Advanced lipoxidation end-products: molecular and cellular effects Reactive carbonyl species (RCS) generated during the lipid peroxidation reactions exhibit a wide range of molecular and biological effects, ranging from protein, DNA, and phospholipid damage to signaling pathway activation and/or alteration.

Most of the biological effects of intermediate RCS, mainly alpha,beta-unsaturated aldehydes, di-aldehydes, and keto-aldehydes, are due to their capacity to react with the nucleophilic sites of proteins, forming advanced lipoxidation end-products (ALEs).

Advanced Lipoxidation End Products (ALEs) are glycated lipids and fats. They’re basically the same thing with minor differences. AGEs are thought to promote aging, inflammation, and worsen many diseases such as diabetes, atherosclerosis, chronic kidney disease, and Alzheimer’s [i] . A review from 2000 summarized additional identifications of different advanced lipoxidation end-products found in atherosclerotic lesions, including MDA-lysine , HNE-lysine , , and levuglandin E2 , which were analysed by both immunohistochemical and chemical techniques . lipid peroxidation products is remarkable.
