Plasma Amino Acids in Prepsychotic Alcoholics

The plasma levels of individual amino acids, amino nitrogen, and ammonia were determined in prepsychotic alcoholics. Low taurine and high glutamic acid levels were the only abnormalities observed. A reduction of the plasma amino acid levels, previously reported, could thus not be confirmed. The possible significance of the elevated plasma glutamic acid level, which might reflect a deterioration of the cerebral metabolism, is discussed.
