Fructose-1,6-bisphosphate is a sugar molecule that plays a crucial role in the process of glycolysis, which is how cells break down glucose to produce energy. It is formed from fructose-6-phosphate through the addition of two phosphate groups, making it a key intermediate in carbohydrate metabolism. This compound is important for regulating energy production in cells. It can be converted into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate, which are further processed to generate ATP, the energy currency of the cell. Its levels can influence the overall rate of glycolysis and energy availability.
