Urinary metabolites of dodecylcyclohexane in Salmo gairdneri: evidence of aromatization and taurine conjugation in trout.
1. The urinary metabolites of 3H-dodecylcyclohexane were investigated in rainbow trout, Salmo gairdneri R. after a single intragastric dose. In 72 h, 14% of the ingested radioactivity was excreted in urine. 2. Cyclohexylacetic acid, 1-hydroxy-, 3-hydroxy- and 4-hydroxy-cyclohexylacetic acids were present in the unconjugated fraction. 3. In the glucuronide fraction (1.2% dose) labelled aglycones were cyclohexylacetic acid and phenylacetic acid. 4. More than 30% of the urinary 3H was present as phenylacetic and cyclohexylacetic acids conjugated with taurine.
