Metabolite Identification
Common Name6-Phosphogluconic acid
Description6-Phosphogluconic acid, also known as 6-phospho-D-gluconate or gluconate 6-phosphate, belongs to the class of organic compounds known as monosaccharide phosphates. These are monosaccharides comprising a phosphated group linked to the carbohydrate unit. 6-Phosphogluconic acid is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 6-Phosphogluconic acid exists in all living species, ranging from bacteria to humans. 6-Phosphogluconic acid can be biosynthesized from gluconolactone and water; which is catalyzed by the enzyme 6-phosphogluconolactonase. In cattle, 6-phosphogluconic acid is involved in the metabolic pathway called the pentose phosphate pathway.
