Glucuronolactone

Glucuronolactone is a white solid odorless compound, soluble in hot and cold water. Its melting point ranges from 176 to 178 °C. The compound can exist in a monocyclic aldehyde form or in a bicyclic hemiacetal (lactol) form. : form of glucuronolactone == Uses ==

Glucuronolactone is an ingredient used in some energy drinks, The European Food Safety Authority (EFSA) has concluded that it is unlikely that glucurono-γ-lactone would have any interaction with caffeine, taurine, alcohol or the effects of exercise. The Panel also concluded, based on the data available, that additive interactions between taurine and caffeine on diuretic effects are unlikely. Glucuronolactone is also metabolized to glucaric acid, xylitol, and L-xylulose, and humans may also be able to use glucuronolactone as a precursor for ascorbic acid synthesis. Glucuronolactone is approved in China and Japan as an over-the-counter "hepatoprotectant", though there is a conspicuous lack of systematic reviews on this use. == Safety ==

The EFSA evaluated the safety of D-glucurono-γ-lactone at the levels used in energy drinks, and determined it to be "not of safety concern." Furthermore research on isolated supplements of glucuronolactone is limited, no warnings appear on the Food and Drug Administration website regarding its potential to cause brain tumors or other maladies. == See also ==
