Cholic acid is an organic substance with a molecular formula of C24H40O5, which exists in the bile of cattle,
sheep, and pigs. It is a colorless flake or white crystalline powder. Some bitter taste, and some sweet feeling after
tasting. The melting point is 198°C, and the specific rotation (c=0.6, ethanol) is +37°. 1g of cholic acid is soluble in
about 300ml of ethanol or acetone, 7ml of glacial acetic acid, and very little soluble in water. The monohydrate is
white flaky crystals. Used in biochemical research and pharmaceutical intermediates. Sodium cholate is a
choleretic, which treats cholecystitis, bile deficiency, and intestinal dyspepsia.

1. Promote the digestion and absorption of lipids
Bile acids contain hydrophilic hydroxyl and carboxyl groups, as well as hydrophobic methyl and hydrocarbon nuclei. At the same time, the steric coordination of hydroxyl and carboxyl groups are both α, so the main configuration of bile acid has both hydrophilicity and hydrophobicity. Tonic promotes lipid emulsification.
2. Inhibit the precipitation of cholesterol in bile (calculi)
Bile acids can also prevent the formation of gallstones. Cholesterol is hardly soluble in water. When bile is discharged into the gallbladder for storage, the bile is concentrated in the gallbladder, and cholesterol is easy to precipitate. However, because the bile contains bile salts and lecithin, cholesterol can be dispersed to form soluble micelles, and it is not easy to precipitate and form stones.
3. The physiological functions of bile acids can be summarized as: influence on bile secretion; influence on lipid absorption; influence on colon function.
(1) It can treat cholecystitis, insufficiency of bile, intestinal indigestion, gallstones, etc.
(2) It can prevent liver disease.
(3) It is an organic acid that can be used to produce vitamin D2 and D3.
