Saccharic acid is a chemical compound with the formula C6H10O8. It is an aldaric acid, naturally occurring in fruits and vegetables.[3]
The salts of saccharic acid are called saccharates or glucarates.
Synthesis
Saccharic acid can be prepared by oxidizing both the aldehydic and primary alcohol groups in an aldose, such as glucose, forming the dicarboxylic acid.[4][5] A suitable reagent for this transformation is boiling 30% nitric acid, resulting in a yield of 50% to 65%.[5] This reaction was first described by German chemist Heinrich Kiliani in 1925.[6]
Uses
Detergents
Script error: No such module "Labelled list hatnote". The sodium salt has found use in dishwasher detergents, where it acts as a chelating agent for calcium and magnesium ions.[6] It is considered more environmentally friendly than phosphates, which are more commonly encountered in detergent formulations.[6][7]
Dietary Supplement
Saccharic acid salts have found use in dietary supplements, where they act as precursors to the β-glucuronidase inhibitor saccharolactone (d-glucaro-1,4-lactone).[3] Some studies have demonstrated saccharolactone to have anticancerogenic properties.[8][9]
