fructose-2,6-bisphosphate

Fructose-2,6-bisphosphate is a small molecule that helps regulate how our cells produce energy. It acts as a signal inside cells to promote glycolysis, the process of breaking down glucose for energy, especially when energy is needed quickly. It also inhibits another pathway (gluconeogenesis) that makes new glucose. By balancing these processes, fructose-2,6-bisphosphate ensures the body efficiently manages blood sugar levels and energy production, especially during fasting or exercise. Its levels are tightly controlled by enzymes, responding to signals like insulin and glucagon to adapt to the body's energy needs.
