Figure 5

Urinary excretion of 6-sulfatoxymelatonin, a serotonin metabolite synthesized in the pineal body. The box and whisker figure illustrates the variation in 6-sulfatoxymelatonin excretion with ingestion of a low-Phe diet in combination with AA-MF or GMP-MF (A). The box represents the middle 50% of 9 subjects (25th–75th percentile) with a solid line showing the median value and a dashed line showing the mean value. Concentrations of 6-sulfatoxymelatonin for each subject with ingestion of AA-MF or GMP-MF are shown (B). Concentrations were measured in aliquots of 24-hr urine and are expressed as ng/mg creatinine or as ug/day for individual subjects.
