  • Title: Daily rhythm in tyrosine concentration in human plasma: persistence on low-protein diets.
    Author: Wurtman RJ, Chou C, Rose CM.
    Journal: Science; 1967 Nov 03; 158(3801):660-2. PubMed ID: 4383136.
    Abstract:
    The concentration of tyrosine in the plasma of normal males varies diurnally. It is lowest (9.5 +/- 0.35 micrograms per milliliter) between 0130 and 0230 hours and rises to a peak of 16.2 +/- 0.82 micrograms per milliliter by 1030 hours. This rhythm persists when subjects are maintained for 2 weeks on a diet that is very low in protein.
