(R)-Methyl 4-((5R,8S,9S,10S,13R,14S,17R)-10,13-Dimethyl-7-oxo-2,5,6,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate is an impurity of Chenodeoxycholic Acid (C291900), a major bile acid in many vertebrates, occurring as the N-glycine and/or N-taurine conjugate. With other bile acids, forms mixed micelles with lecithin in bile which solubilize cholesterol and thus facilitates its excretion.
