SUMMARY

The daily rhythm of plasma tyrosine was studied in obese subjects during total fasting, because of the relative constancy of the metabolic processes in this state. The plasma levels of tyrosine showed circadian fluctuations which were similar, although less pronounced, to those observed by other authors. The lowest values occurred at 03.00 h and the highest at 08.00 h with a second rise at 19.00 h.
