D-Saccharic acid potassium salt is a compound formed from oxidizing sugars which can be used to test for the presence of hepatic enzyme induction. Studies indicate that D-glucuronolactone dehydrogenase oxidizes D-Saccharic acid potassium salt into D-glucaro-l4;63-dilactone.

Homocitrulline is a metabolite that can be detected in larger amounts in the urine of individuals with urea cycle disorders. The accumulation of carbamyl phosphate due to a depleted supply of ornithine for the urea cycle may be responsible for the enhanced synthesis of homocitrulline and homoarginine in some cases.

(3R,5R)-1-(4-Hydroxyphenyl)-7-phenyl-3,5-heptanediol is an antiemetic found in Alpinia officinarum that significantly inhibits copper sulfate-induced emesis in young chicks (with an inhibition rate of 50.9% at a dose of 20 mg/kg and 37.7% at a dose of 50 mg/kg).
