Common NameBeta-D-Fructose 6-phosphate
DescriptionBeta-D-Fructose 6 phosphate (b-F6P) is the beta-anomer of fructose-6-phosphate. There are two anomers of fructose 6 phosphate, the alpha anomer and the beta anomer. Specifically, beta-D-fructose 6-phosphate is fructose sugar phosphorylated on carbon 6. Beta-D-Fructose 6-phosphate is a substrate for Fructose-1,6-bisphosphatase, Pyruvate kinase (isozymes R/L), Hexokinase (type I), Fructose-bisphosphate aldolase A, L-lactate dehydrogenase B chain, Glyceraldehyde-3-phosphate dehydrogenase (liver) and Transaldolase.

Enzymes

General function:
Involved in ATP binding
Specific function:
Catalyzes the initial step in utilization of glucose by the beta-cell and liver at physiological glucose concentration. Glucokinase has a high Km for glucose, and so it is effective only when glucose is abundant. The role of GCK is to provide G6P for the synthesis of glycogen. Pancreatic glucokinase plays an important role in modulating insulin secretion. Hepatic glucokinase helps to facilitate the uptake and conversion of glucose by acting as an insulin-sensitive determinant of hepatic glucose usage.
