APPLICATIONS

Bile is a bitter, yellow to greenish fluid composed of glycine or taurine conjugated bile salts, cholesterol, phospholipid, bilirubin diglucuronide, and electrolytes. It is secreted by the liver and delivered to the duodenum to aid the process of digestion and fat absorption by emulsification of fat products in the upper small intestine. They play role dissolving cholesterol and accretes into lumps in the gall bladder, forming gallstones. Bile's bicarbonate constituents serves for alkalinizing the intestinal contents. Bile is responsible for as the route of excretion for hemoglobin breakdown products (bilirubin). Excretion of bile salts by liver cells and secretion of bicarbonate rich fluid by ductular cells in response to secretin are the major factors which normally determine the volume of secretion. Bile acids are liver-generated steroid carboxylic acids. The primary bile acids (cholic and chenodeoxycholic acid) are conjugated with either glycine or taurine in the form of taurocholic acid and glycocholic acid. The secondary bile acids (deoxycholic, lithocholic, and ursodeoxycholic acid) are formed from the primary bile acids by the action of intestinal bacteria. They are soluble in alcohol and acetic acid. The lithocolyl conjugates are relatively insoluble; excreted mostly in the form of sulfate esters like sulfolithocholylglycine. Most of the bile acids are reabsorbed and returned to the liver via enterohepatic circulation, where, after free acids are reconjugated, they are again excreted.
