Glucuronic acid equally painful responses to decreasingly noxious (irritating) stimuli, eventually resulting in considerable agony from stimuli which wouldn't cause any amount of pain to most individuals. Determination of urinary steroids and of steroid conjugates in blood. Ethyl glucuronide and ethyl sulfate are excreted in urine as metabolites of ethanol and are used to monitor alcohol use or dependence. Glucuronic acid and gluconic acid are fermentation products in Kombucha tea. Glucuronic acid is a precursor of ascorbic acid (vitamin C, formerly called as L-hexuronic acid). Ascorbate can be biosynthesized by higher plants, algae, yeast and most animals. An adult goat produces ~13
Vitamin C -Galactose reacts with the enzyme -galactose dehydrogenase, whereby the lactone ring opens and forms again but with between the carbonyl on C1 and hydroxyl group on the C4, resulting in -galactonolactone. -Galactonolactone then reacts with the mitochondrial flavoenzyme -galactonolactone dehydrogenase. to produce ascorbic acid. -Ascorbic acid has a negative feedback on -galactose dehydrogenase in spinach. Ascorbic acid efflux by embryo of dicots plants is a well-established mechanism of iron reduction, and a step obligatory for iron uptake. All plants synthesize ascorbic acid. Ascorbic acid functions as a cofactor for enzymes involved in photosynthesis, synthesis of plant hormones, as an antioxidant
