cukorfoszát

Cukorfoszát, also known as fructose-6-phosphate (F6P), is a vital intermediate compound in the metabolism of carbohydrates, playing a crucial role in both glycolysis and gluconeogenesis. It is a phosphorylated sugar derived from fructose. In glycolysis, the pathway that breaks down glucose to produce energy, fructose-6-phosphate is formed from fructose-1-phosphate. This conversion is catalyzed by the enzyme phosphofructokinase-1, a key regulatory enzyme in glycolysis. Cukorfoszát is then further processed to fructose-1,6-bisphosphate.

In gluconeogenesis, the process of synthesizing glucose from non-carbohydrate precursors, cukorfoszát serves as a critical intermediate as well. It is formed from fructose-1,6-bisphosphate and is subsequently converted back to glucose-6-phosphate, which can then be dephosphorylated to glucose. The interconversion between these phosphorylated sugars allows the cell to efficiently manage glucose levels and energy production. Cukorfoszát is found in all living organisms, highlighting its fundamental importance in cellular energy metabolism. Its presence and concentration are tightly regulated to meet the metabolic demands of the cell.
