  <name>7a-Hydroxy-cholestene-3-one</name>
  <description>7a-Hydroxy-cholestene-3-one is a metabolite in bile acid synthesis.  It is derived from 7a-hydroxy-cholesterol and can be further metabolized to 7a,12a,-dihydroxy-cholest-4-en-3-one. Analysis of 7a-Hydroxycholestene-3-one (HCO) in serum may serve as a novel, simple, and sensitive method for the detection of bile acid malabsorption in patients with chronic diarrhea of unknown origin (PMID 9952217) [HMDB]</description>
