Methylglyoxal is a toxic endogenous substance known to react with proteins to form advanced glycation endproducts, which accumulated in the body during aging. Hyperglycemic can accelerate the accumulation of AGEs, and it has been link to the development of diabetic complications.

由於Methylglyoxal在体内会形成高阶糖化终产物,而这些终产物在老化过程中会大量蓄积且高血糖会加速其蓄积,而与糖尿病晚期的并发症有相当的关联性。

Secondly, the silver based catalysts modified by phosphorus, zirconium, zinc, potassium and so on using molecular sieve as carrier, which were produced by ion-exchange method, had also good catalytic performance for 1,2-propane glycol oxidation to methylglyoxal. The conversion of 1,2-propane glycol and the selectivity of methylglyoxal were both high, and the impurity such as formaldehyde and acetaldehyde in the product is little.
