Sedoheptulose 7-phosphate is an intermediate in the

pentose phosphate pathway The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt and the HMP Shunt) is a metabolic pathway parallel to glycolysis. It generates NADPH and pentoses (5-carbon sugars) as well as ribose 5-p ...

. It is formed by

transketolase Transketolase (abbreviated as TK) is an enzyme that is encoded by the TKT gene. It participates in both the pentose phosphate pathway in all organisms and the Calvin cycle of photosynthesis. Transketolase catalyzes two important reactions, which ...

and acted upon by

transaldolase Transaldolase is an enzyme () of the non-oxidative phase of the pentose phosphate pathway. In humans, transaldolase is encoded by the ''TALDO1'' gene. The following chemical reaction is catalyzed by transaldolase: : sedoheptulose 7-phospha ...

. Sedoheptulokinase is an enzyme that uses

sedoheptulose Sedoheptulose or pseudoheptulose or D-''altro''-heptulose is a ketoheptose—a monosaccharide with seven carbon atoms and a ketone functional group. It is one of the few heptoses found in nature, and is found in various fruits and vegetabl ...

and ATP to produce ADP and sedoheptulose 7-phosphate. Sedoheptulose-bisphosphatase is an enzyme that uses sedoheptulose 1,7-bisphosphate and H₂O to produce sedoheptulose 7-phosphate and phosphate.
