Analysis of Advanced Glycation End Products (AGEs)
摘要
Advanced glycation end products (AGEs) are formed both exogenously in foods and endogenously through metabolic processes. Their key precursors, glyoxal (GO), methylglyoxal (MGO), and 3-deoxyglucosone (3-DG), are reactive dicarbonyl compounds. This study outlines the analytical procedures for quantifying GO, MGO, CML, CEL, and furosine using high-performance liquid chromatography (HPLC) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Sample preparation includes derivatization, extraction, and purification steps specific to each analyte. The described methods enable precise detection of AGEs and their precursors in complex matrices.
