DescriptionSedoheptulose 7-phosphate belongs to the class of organic compounds known as monosaccharide phosphates. These are monosaccharides comprising a phosphated group linked to the carbohydrate unit. Sedoheptulose 7-phosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). Sedoheptulose 7-phosphate exists in both E. coli (prokaryote) and yeast (eukaryote). In yeast, sedoheptulose 7-phosphate is involved in the metabolic pathway called the xylitol degradation pathway.
