Some Biochemical Consequences of Feeding Excesses of Phenylalanine to Rats*

Protein Activators, Learning and Neural Changes in Phenylketonuric Rats*

“…The finding that plasma Phe was not elevated at the end of the experiment is consistent with the observation by Rendina (1967) who finds a decrease in the level of serum phenylalanine with age, while in weanling rats, after one week on 5 per cent L-phenylalanine diet, Kerr and Waisman (1967) measured 17.6±11.3 mg per cent phenylalanine in the plasma. The levels remained elevated up to week 12.…”
