Gluconic acid
Gluconic Acid
Gluconic acid (/ɡluːˈkɒnɪk/ gloo-KON-ik) is an organic compound with the formula C6H12O7. It is a carboxylic acid that is derived from glucose, hence the name "gluconic," which is a combination of "glucose" and "onic," a suffix used in the names of acids.
Etymology
The term "gluconic acid" is derived from the word "glucose," which comes from the Greek word "glykys," meaning "sweet," and the suffix "-onic," which is used in the names of acids. The term was first used in the late 19th century.
Chemical Structure
Gluconic acid is a polyhydroxy acid (PHA) with a six-carbon chain, which is the same length as glucose. It has five hydroxyl groups and one carboxyl group. The carboxyl group is at the end of the chain, making gluconic acid an alpha-hydroxy acid (AHA).
Production
Gluconic acid is produced naturally in fruits, honey, and wine through the process of fermentation. It can also be produced industrially through the oxidation of glucose using glucose oxidase.
Uses
Gluconic acid is used in various industries, including food, pharmaceutical, and cleaning. In the food industry, it is used as a pH regulator, sequestrant, and leavening agent. In the pharmaceutical industry, it is used in the formulation of pharmaceutical drugs to improve their solubility. In the cleaning industry, it is used as a chelating agent to bind and remove metal ions.
