D-Sedoheptulose-7-phosphate is an intermediate in the pentose phosphate pathway.
1,2 In this pathway, transaldolase catalyzes the transfer of a three carbon dihydroxyacetone moiety from D-sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate to generate D-fructose-6-phosphate. D-Sedoheptulose-7-phosphate is also an intermediate in carbon fixation in photosynthetic organisms, as well as in the biosynthesis of lipopolysaccharide, amino acids, secondary metabolites, and antibiotics.
