Calcium D-Glucarate (hydrate) (Synonyms: Calcium D-Saccharate, D-Glucaric Acid Calcium Salt, D-Saccharic Acid Calcium Salt)

Calcium D-glucarate is the calcium salt form of D-glucaric acid.¹ D-Glucaric acid is an end product of D-glucuronic acid metabolism in mammals that has also been found in fruits and vegetables and has anticancer activity.² It is produced by the oxidation of D-glucuronic acid and is a precursor in the biosynthesis of the β-glucuronidase inhibitor D-glucaro-1,4-lactone in vivo.¹ Dietary administration of calcium D-glucarate (10% w/w) reduces tumor growth in a rat model of mammary tumorigenesis induced by 7,12-dimethylbenz[a]anthracene (DMBA).³ Urinary D-glucaric acid levels have been used as a marker for xenobiotic-induced phase II metabolism in patients with rheumatoid arthritis or individuals exposed to environmental toxicants.^4,5
