title: 3-Amino-2-piperidone in the urine of patients with hyperornithinemia.
abstract: 3-Amino-2-piperidone, a delta-lactam of ornithine, has been detected in the urine of a number of patients with hyperornithinemia. The distinctive yellow colour formed with a ninhydrin-cadmium reagent should help in the detection of hyperornithinemia by urinary chromatography.
