Glucose 6-phosphate to fructose 6-phosphate
WebConsider the following isomerization reactions of some simple sugars and values for their standard Gibbs free energy ΔG ∘:. reaction A: glucose-1-phosphate glucose-6-phosphate, ΔG ∘ = −7.28 kJ/mol. reaction B: fructose-6-phosphate glucose-6-phosphate, ΔG ∘ = −1.67 kJ/mol. Calculate the equilibrium constant K for the … WebBackground: Glucose-6-phosphate isomerase (GPI) is a glycolytic-related enzyme that interconverts glucose-6-phosphate and fructose-6-phosphate in the cytoplasm. This protein is also secreted into the extracellular matrix by cancer cells and is, therefore, also called autocrine motility factor (AMF).
