It has a role as a bacterial metabolite. It is a carbobicyclic compound, a 5-hydroxy monocarboxylic acid, an alicyclic ketone, an oxo monocarboxylic acid and a secondary alcohol. It is a conjugate acid of a 3-[(3aS,4S,5R,7aS)-5-hydroxy-7a-methyl-1,5-dioxo-octahydroinden-4-yl]propanoate. It derives from a hydride of a hydrindane."}]
