The biochemical property of bile acids. (A) Cholesterol and cholic acid structure. Compared to cholesterol, cholic acid has hydroxyl groups at the C7 and C12 position, a shortened and oxidized sterol side chain, and C5-C6 double bond saturation; (B) illustration of glycine and taurine conjugated bile acids. Bile acids conjugation is mediate by the bile acid CoA ligase (BAL) and the bile acid CoA: amino acid N-acetyltransferase (BAAT).
