D-景天酮糖7-磷酸是许多途径中的代谢物，例如戊糖磷酸途径中的中间产物，以及光合生物体中的碳固定。D-七酮糖是戊糖磷酸途径（PPP）的中间产物。D-景天酮糖-7-磷酸有助于NADPH的产生和核苷酸合成中核糖残基的形成。转醛醇酶（TALSDO1）缺陷的个体中Sedoheptulose-7-磷酸水平可能增加。 D-Sedoheptulose 7-phosphate is a metabolite in a number of pathways, e.g. an intermediate in the pentose phosphate pathway, and the carbon fixation in photosynthetic organisms. D-Sedoheptulose is a pentose phosphate pathway (PPP) intermediate. D-Sedoheptulose-7-phosphate contributes to the generation of NADPH and the formation of ribose residues of nucleotide synthesis. Sedoheptulose-7-phosphate levels may be increased in individuals with defects in transaldolase (TALSDO1).
