Sedoheptulose 7-phosphate is an intermediate in the pentose phosphate pathway. Sedoheptulose 7-phosphate is an intermediate in the pentose phosphate pathway. It is formed by transketolase and acted upon by transaldolase. Sedoheptulokinase is an enzyme that uses sedoheptulose 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.
