Tryptophan metabolism and urinary quinoline bases in the greyhound.
Three quinoline bases may be found in greyhound urine. 2-aminomethylquinoline is excreted in fresh urine and two others, quinaldine and 2-hydroxymethylquinoline, are formed as the urine decays. Radiolabelling was employed to demonstrate that these bases are derived from the amino acid tryptophan.
