The reaction of methylglyoxal with polypeptides is accompanied by an electron spin resonance absorption in the free radial region. Analysing the interaction of methylglyoxal with poly-L-lysine we found that methylglyoxal polymer formation is a major process in our system. The electron spin resonance signal seems to originate both from the polymer itself and its interaction with the polypeptide. Nuclear magnetic resonance measurements show that the methylglyoxal polymer interacts with the polypeptide via the NH groups of peptide bonds.
甲基乙二醛与多肽的反应伴随着自由基区域的电子自旋共振吸收。通过分析甲基乙二醛与聚-L-赖氨酸的相互作用，我们发现甲基乙二醛聚合物的形成是我们系统中的主要过程。电子自旋共振信号似乎既源于聚合物本身，也源于其与多肽的相互作用。核磁共振测量表明，甲基乙二醛聚合物通过肽键的NH基团与多肽相互作用。
