Fructose 6-phosphate is a simple sugar molecule that plays a crucial role in the metabolic pathways of living organisms. It is an intermediate in the glycolysis process, where glucose is broken down to produce energy. This compound is formed from glucose 6-phosphate through the action of the enzyme phosphoglucose isomerase. In addition to its role in energy production, fructose 6-phosphate is also involved in the synthesis of other important biomolecules. It can be converted into fructose 1,6-bisphosphate, which is a key regulator in the glycolytic pathway. This regulation helps maintain the balance of energy production in cells.
