Abstract
Fructose-1-phosphate, the product of fructose phosphorylation by fructokinase, favours glucose phosphorylation by glucokinase, at the intervention of a regulatory protein. Glucose confers to glucokinase positive cooperativity, towards fructose. These reciprocal effects are operative in hepatocytes and pancreatic islets. They could optimize their glucostatic function.
