Probing Protein Glycation by Chromatography and Mass Spectrometry: Analysis of Glycation Adducts
Glycation is a non-enzymatic post-translational modification of proteins, formed by the reaction of reducing sugars and α-dicarbonyl products of their degradation with amino and guanidino groups of proteins. Resulted early glycation products are readily involved in further transformation, yielding a heterogeneous group of advanced glycation end products (AGEs). Their formation is associated wit...
متن کاملMeasurement of protein glycation, glycated peptides, and glycation free adducts.
Protein glycation adducts, early glycation adducts, such as N(epsilon)-fructosyl-lysine, and advanced glycation end products (AGEs) are uremic toxins. Glycation adducts are found in plasma and tissue proteins (glycation adduct residues), in peptides (glycation adduct peptide residues), and glycated amino acids (glycation free adducts). The latter two analyte groups arise from proteolysis of gly...
متن کاملProtein Glycation in Diabetes as Determined by Mass Spectrometry
Diabetes is a common endocrine disorder characterized by hyperglycemia leading to nonenzymatic glycation of proteins, responsible for chronic complications. The development of mass spectrometric techniques able to give highly specific and reliable results in proteome field is of wide interest for physicians, giving them new tools to monitor the disease progression and the possible complications...
متن کاملIdentification of glycation at the N-terminus of albumin by gas chromatography-mass spectrometry.
Amino groups in human albumin are modified in vivo by glucose in a non-enzymic reaction, and previous studies have implicated lysine residues as exclusive participants. An investigation using g.c.-m.s. was undertaken to ascertain whether or not the N-terminus was also involved. Appropriate model compounds [N-(1-deoxyglucitol-1-yl) and N-(1-deoxymannitol-1-yl) adducts of aspartic acid] were synt...
متن کاملPerchloroethylene Analysis by Chemical Oxidation and Determination of Intermediate Products by Gas Chromatography, Mass Spectrometry
Abstract Background and Objective: Perchloroethylene (PCE) is a chlorinated hydrocarbon used as a solvent in many industrial processes. In contaminated water and soil a great deal of PCE is found. This study aimed to determine the rate of decomposition of PCE occurred after advanced oxidation. Material and Methods: In this descriptive-analytic study conducted (2011) in public health faculty...
