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 K2 by this vitamin group were revealed to be much more complex. K vitamins play an essential role as cofactor for the enzyme γ-glutamyl carboxylase, which is involved in vitamin K-dependent carboxylation of the gla domain in "Gla proteins" (i.e., in conversion of peptide-bound glutamic acid (Glu) to γ-carboxy glutamic acid (Gla) in these proteins). Carboxylation of these vitamin K-dependent Gla-proteins, besides being essential for the function of the protein, is also an important vitamin recovery mechanism since it serves as a recycling pathway to recover vitamin K from its epoxide metabolite (KO) for reuse in carboxylation. Several human Gla-containing proteins
