Methylglyoxal is an alpha-ketoaldehyde and dicarbonyl formed in cells as a side product of normal metabolism. Endogenously produced dicarbonyls, such as methylglyoxal, are involved in numerous pathogenic processes in vivo, including carcinogenesis and advanced glycation end-product formation; advanced glycation end-products
