Description

Application

Methylglyoxal 1,1-dimethyl acetal was used in the synthesis of methylglyoxal via hydrolysis in the presence of H₂SO₄. It was used to investigate the effects of methylglyoxal-mediated glycation on the structure, thermal stability and enzyme activity of yeast enolase in vivo.
