Phosphorylated Saccharides (1) (NH2P-50 4E)

Glucose can be anearobically decomposed into lactic acid and ethanol. This decomposing process is called as glucolytic pathway. In this pathway, some products such as glucose-1-phosphate, glucose-6-phosphate, fructose-6-phosphate, fructose-1,6-bisphosphate, etc. are produced as intermediary products. Here, glucose-1-phosphate, fructose-6-phosphate and glucose-6-phosphate are analyzed using Asahipak NH2P-50 4E by ion-exchange mode. It was confirmed that the retention is stronger and separation is better by using lower concentration phosphate buffer.
