Title: D-Glucuronic Acid
CAS Registry Number: 6556-12-3
Molecular Formula: C6H10O7
Molecular Weight: 194.14
Percent Composition: C 37.12%, H 5.19%, O 57.69%
Literature References: Widely distributed in the plant and animal kingdoms. Usually occurs in "paired" form, i.e. as a glycosidic combination with phenols, alcohols, etc. Such glucuronides form in the liver to detoxify poisonous hydroxyl-containing substances. The glucuronides present in normal urine are those of phenol, cresol, and indoxyl. After the ingestion of poisons such as morphine, chloral hydrate, camphor, or turpentine, glucuronides formed with the poison or its hydroxylated derivatives appear in the urine.
