  <name>Gluconic acid</name>
  <description>Gluconic acid, also known as D-gluconate or dextronic acid, belongs to the class of organic compounds known as sugar acids and derivatives. Sugar acids and derivatives are compounds containing a saccharide unit which bears a carboxylic acid group. Gluconic acid is a drug which is used for use as part of electrolyte supplementation in total parenteral nutrition [fda label]. Gluconic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Gluconic acid exists in all living species, ranging from bacteria to humans. In cattle, gluconic acid is involved in the metabolic pathway called the pentose phosphate pathway.</description>
