title: Formation of sorbitol 6-phosphate by bovine and human lens aldose reductase, sorbitol dehydrogenase and sorbitol kinase.
abstract: Formation of sorbitol 6-phosphate by bovine and human lens aldose reductase and sorbitol dehydrogenase by the reduction of glucose 6-phosphate and fructose 6-phosphate, respectively, has been demonstrated. The reaction product has been identified by Dowex-formate column chromatography, gas chromatography and mass spectrometry. Sorbitol 6-phosphate can also be formed by the phosphorylation of sorbitol by lens sorbitol kinase in the presence of ATP.
