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.This publication has 8 references indexed in Scilit:
