Heptulosonate is a type of organic compound that belongs to the family of hexuronic acids. It is a 7-carbon sugar derivative, specifically a hepturonic acid, found in the pericarp of citrus fruits. Heptulosonates are known for their roles in plant defense mechanisms and have been investigated for their potential antioxidant and antimicrobial properties.
