Abstract

The α-dicarbonyl compounds formed in the degradation of glucose and fructose were analyzed by HPLC using 2, 3-diaminonaphthalene as derivatizing reagent, and identified as glucosone (GLUCO), 3-deoxyglucosone (3DG), 3-deoxyxylosone (3DX), tetrosone (TSO), triosone (TRIO), 3-deoxytetrosone (3DT), glyoxal (GO), and methylglyoxal (MGO). The results suggest that α-dicarbonyl compounds were formed from glucose via non-oxidative ...
