Abstract
When specifically labeled glutamate-1-14C was provided to 4-day-old rose cells, 87.6% of the 14C in glutamate recovered from protein was in the number 1 carbon atom of the glutamate molecule. It was concluded that newly absorbed glutamate was incorporated directly into protein without any prior metabolism.
A double labeling study with acetate-U-14C and glutamate-U-3H showed the availability of absorbed glutamate for protein synthesis was equal to that of endogenously synthesized glutamate.
