3-Deoxyglucosone is one of the major cytotoxic intermediates in the Maillard reaction. Adrenal glands showed the highest NADPH-linked 3-deoxyglucosone reductase activity of dog tissues. The enzyme was purified to homogeneity from the adrenal glands, and demonstrated to be structurally, functionally and immunologically identical with aldose reductase, which comprises about 6% of the soluble adrenal proteins.
3-脱氧葡萄糖酮是迈拉德反应中主要的细胞毒性中间产物之一。肾上腺显示出狗组织中最高的NADPH依赖性3-脱氧葡萄糖酮还原酶活性。该酶从肾上腺中被纯化至均一状态,并被证明在结构上、功能上以及免疫学上与醛糖还原酶相同,后者约占肾上腺可溶性蛋白质的6%。
