摘 要: 通过对果糖和葡萄糖的氧化反应机理的探讨,烯二醇的形成是单糖氧化的决定速率步骤,单糖的氧化速率等于它的烯醇化速率,果糖的烯醇化速率是葡萄糖的11.3倍,解释果糖在与Tol-lens,Fehling。 Through the study of mechnism of oxidation of fructose and glucose. The formation of enediol is the rate-determining step in the oxidation of monosaccharide. The rates of oxidation of monosaccharides equal correspondingly to their rates of enolization. The rate of enolization of fructose is 11. 3 times that of glucose. This might lead to that fructose reacts much more easily than glucose with Tollens, Fehling or Benedict reagent.
