Gluconic Acid vs. Glucuronic Acid: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on December 5, 2023
Gluconic acid is a mild organic acid derived from glucose oxidation, whereas glucuronic acid is a carbohydrate acid formed by oxidizing the aldehyde group of glucose.

Key Differences

Gluconic acid is produced by the oxidation of the primary alcohol group of glucose to a carboxylic acid. In contrast, glucuronic acid results from the oxidation of the aldehyde functional group at the end of the glucose molecule.
In terms of chemical structure, gluconic acid retains the aldehyde group of glucose, while glucuronic acid has a carboxylic acid group replacing the aldehyde group. This structural difference impacts their roles and functions in biological and industrial applications.
Gluconic acid is known for its mild acidity and is used in food and pharmaceutical industries as an acidity regulator and a cleaning agent. Glucuronic acid plays a significant role in the body’s detoxification processes, conjugating with toxins to make them more water-soluble and easier to excrete.
In the pharmaceutical industry, gluconic acid is used in mineral supplements due to its chelating properties. Glucuronic acid, on the other hand, is important in pharmacology for drug conjugation and metabolism.
Gluconic acid is often found in various foods naturally or as an additive, contributing to taste and stability. Glucuronic acid is essential in the metabolism of complex carbohydrates and is not typically used as a food additive.
