Definition

ChEBI: (-)-isomenthone is an isomenthone. It is an enantiomer of a (+)-isomenthone.

Metabolism

d-Isomenthone undergoes reduction in the rabbit, since d-isomethylglucuronide is excreted in the urine. The other possible reduction product, d-neoisomenthol is not excreted (Williams, 1959).
