Natural Product Identification
Common Name12-Ketodeoxycholic acid
Description12-Ketodeoxycholic acid, also known as 12-dehydrodeoxycholate or 12-ketolithocholate, belongs to the class of organic compounds known as monohydroxy bile acids, alcohols and derivatives. These are bile acids, alcohols or any of their derivatives bearing a hydroxyl group. The distinction between different bile acids is minute, depends only on presence or absence of hydroxyl groups on positions 3, 7, and 12. 12-Ketodeoxycholic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 12-Ketodeoxycholic acid exists in all living organisms, ranging from bacteria to humans. Bile acids are steroid acids found predominantly in bile of mammals. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. 12-Ketodeoxycholic acid was first documented in 1988 (PMID: 3133222). Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit (PMID: 2545348) (PMID: 8173925).
