title: [Methylglyoxal: metabolism and biological activity].
abstract: The enzymic formation of methylglyoxal from dihydroxyacetone phosphate and aminoacetone (metabolites of carbohydrates and proteins) is considered. Methylglyoxal transformation into lactic and pyruvic acids is related to energy metabolism, catabolism and anabolism dissociation processes in carbohydrates and proteins, and, probably, to maintenance of asymmetrical entropy in vivo on the constant level. Attention is paid to the methylglyoxal inhibition of enzymes, its interaction with glutathione and polyamines affecting the mechanisms regulating protein synthesis and cellular division. The methods for obtaining and quantitative determination of methylglyoxal are described.
