Abstract
The oxidation of D-glucose 6-phosphate by lead tetraacetate in cold acetic–propionic acid produces D-erythrose 4-phosphate contaminated with a small proportion of D-glyceraldehyde 3-phosphate. The product is a suitable substrate for certain enzymic studies, as illustrated by its use in the assay of transaldolase and transketolase. D-Erythritol 4-phosphate may readily be obtained in high yield by reducing the crude oxidation mixture with sodium borohydride. Oxidation of D-fructose 6-phosphate with 1 mole of lead tetraacetate gives chiefly D-erythrose 4-phosphate, whereas oxidation with 2 moles produces mainly D-glyceraldehyde 3-phosphate. The stability of D-erythrose 4-phosphate under a variety of conditions was also examined.
