Molecular Structure


Glucuronolactone is metabolized to glucaric acid, xylitol, and L-xylulose, and humans may also be able to use glucuronolactone as a precursor for ascorbic acid synthesis.

The liver uses glucose to create glucuronolactone, which inhibits the enzyme B-glucuronidase (metabolizes glucuronides), which should cause blood-glucuronide levels to rise. Glucuronides combine with toxic substances, such as morphine and depot medroxyprogesterone acetate, by converting them to water-soluble glucuronide-conjugates which are then excreted from the body. Glucuronolactone is a popular ingredient in applications for detoxification.
