Peroxyl Radicals Are Essential Reagents in the Oxidation Steps of the Maillard Reaction Leading to Generation of Advanced Glycation End Products

Spiteller, Gerhard·2008·Annals of the New York Academy of Sciences

Abstract

Polyunsaturated fatty acids (PUFAs) are incorporated in all membranes of mammalian and plant cells and are extremely sensitive to oxygen. This property is used in nature to respond to any changes in cell membrane structure. In the first step of a response, lipid hydroperoxide molecules are generated. An increasing impact switches the enzymatic reaction to a nonenzymatic one by generation of lipid peroxyl radicals, which attack sugars by oxidation. In the course of these reactions, hydrogen peroxyl radicals are generated, resembling lipid peroxyl radicals in their reactivity. The reactions induced by these radicals are not under genetic control, they attack nearly all types of biological molecules (such as proteins, lipids, and sugars), and are responsible for the deleterious cell alterations in aging and age‐related diseases (such as diabetes, Alzheimer's disease, or atherosclerosis) and probably also in autoimmune diseases, which involve sugars at the cell membranes. Lipid peroxidation processes are induced by heating fats, meat, and other nutritional products. The oxidation products generated by consumption of heated food cause damage of mammalian cells. The deleterious reactions can be partly reduced by consumption of plants and/or algae. These contain, among other well‐known antioxidants, furan fatty acids, which are important scavengers of peroxyl radicals.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • There is substantial local production of inflammatory mediators in organs affected by insulin resistance.

    “As described above, there is substantial local production of inflammatory mediators in organs affected by insulin resistance.”
  • The parallelism between down-regulation of inflammation-related genes and reduction in adiposity and adipocyte diameter by n-3 PUFA treatment suggests a positive relationship between adipose cell size and adipose tissue inflammation.

    “The parallelism between the down-regulation of these genes and the reduction in adiposity and adipocyte diameter by n-3 PUFA treatment suggests a positive relationship between adipose cell size and adipose tissue inflammation, agreeing with other observations (31,66) .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
