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
L-gulonolactone oxidase deficiency living in a malarial infested environment". He based his observation on evidence which indicates that G6PD deficient individuals display enhanced sensitivity to ascorbic acid induced hemolysis. Studies of human diseases have benefited from the availability of small laboratory animal models. However, the tissues of animal models with a GULO gene generally have high levels of ascorbic acid and so are often only slightly influenced by exogenous vitamin C. Guinea pigs, for instance, are a popular human model but lost the ability to synthesize L-gulono-gamma-lactone oxidase 20 million years ago. This is a major handicap for studies involving the endogenous
