D-Glucosone 6-phosphate (D-arabino-hexos-2-ulose 6-(dihydrogen phosphate)) was prepared from D-glucosone (D-arabino-hexos-2-ulose) by enzymatic conversion with hexokinase. The isomeric composition of D-glucosone 6-phosphate in aqueous solution was quantitatively determined by NMR spectroscopy and compared to D-glucosone. The main isomers are the alpha-anomer (58%) and the beta-anomer (28%) of the hydrated pyranose form, and the beta-D-fructofuranose form (14%).
6-磷酸-D-葡萄糖醛酮（D-阿拉伯己糖-2-酮糖6-（磷酸二氢酯））由D-葡萄糖醛酮（D-阿拉伯己糖-2-酮糖）通过己糖激酶的酶促转化制备而成。通过核磁共振光谱法定量测定了水溶液中6-磷酸-D-葡萄糖醛酮的异构体组成，并与D-葡萄糖醛酮进行了比较。主要异构体为水合吡喃糖形式的α-端基异构体（58%）和β-端基异构体（28%），以及β-D-呋喃果糖形式（14%）。
