Alternative definition : KEGG: Bile acids are steroid carboxylic acids derived from cholesterol in vertebrates.
The primary bile acids, cholic acid and chenodeoxycholic acid, are synthesized in
the liver and conjugated with taurine or glycine before secretion via bile into the
intestine. The conversion from cholesterol to cholic and chenodeoxycholic acids involves
four steps: 1) the initiation of synthesis by 7alpha-hydroxylation of sterol precursors,
2) further modifications to the ring structures, 3) side-chain oxidation and shortening
(cleavage) by three carbons, and 4) conjugation of the bile acid with taurine or glycine.;
