Sedoheptulose 7-phosphate
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.

Sedoheptulose-bisphosphatase
Sedoheptulose-bisphosphatase (also sedoheptulose-1,7-bisphosphatase or SBPase, EC number 3.1.3.37; systematic name sedoheptulose-1,7-bisphosphate 1-phosphohydrolase ) is an enzyme that catalyzes the removal of a phosphate group from sedoheptulose 1,7-bisphosphate to produce sedoheptulose 7-phosphate.

Sedoheptulokinase
In enzymology, a sedoheptulokinase () is an enzyme that catalyzes the chemical reaction
ATP + sedoheptulose ADP + sedoheptulose 7-phosphate
Thus, the two substrates of this enzyme are ATP and sedoheptulose, whereas its two products are ADP and sedoheptulose 7-phosphate.

Cetoniacytone A
Feeding experiments conducted by Zeeck and co-workers established the synthesis of Cetoniacytone A to proceed via the pentose phosphate pathway with sedoheptulose Sedoheptulose-7- phosphate first undergoes a cyclization catalyzed by 2-epi-5-epi-valiolone synthase (CetA) yielding 2-epi-5-epi-valiolone.
