Description
High Performance Liquid Chromatography (HPLC) Method for Analysis of Glucose 6-Phosphate , Glucose 1- Phosphate .
Structural isomer separation poses a challenging task when using reverse-phase chromatography. However both glucose variants, which only differ to which carbon the phosphate group is attached to, can be separated in HPLC isocratically on a reverse-phase mixed-mode anion-exchange Newcrom B column. What differentiates, the Newcrom B phase from other silica-based Analysis of glucose phosphate is important because glucose-6-phosphate is the product of the first step in glycolysis metabolic pathway and glucose-1-phosphate is the first step in glycogenolysis. Glucose-6-phosphate is converted to glucose-1-phosphate and vice versa by the phosphoglucomutase enzyme in biological systems.
