“…[3][4][5] Glutamic acid and its derivatives, glutamine and -aminobutyric acid (GABA), play a dominant role in maintaining and regulating normal physiological processes of the central nervous system (CNS Age and Sex.-The ages on the initial ad¬ mission to the hospital ranged from 1 to 14 years.

“…Mit Ausnahme der y-Amino-buttersäure gilt dies auch für diejenigen Stoffe, die dort besondere Funktionen erfüllen, wie freie Glutaminsäure. Insgesamt unterscheidet sich das Aminosäurespektrum der Proteinaminosäuren erheblich von dem der freien Aminosäuren des Gehirns 23 und des Liquor cerebrospinalis 22 Aus diesen Zahlen geht hervor, daß die aliphatischen Monoaminomonocarbonsäuren im Gehirn wohl im wesentlichen als Bausteine höher-molekularer Stoffe betrachtet werden müssen. Eine Eigenfunktion als freie Aminosäuren ist nicht nur nicht bekannt, sondern danach nicht wahrscheinlich.…”

“…The best results were obtained by electrophoresis in formic acidacetic acid, followed by chromatography in butanol-acetic acid in the second dimension. This system has been applied to the amino acids and amines in cerebrospinal fluid (Knauff, Mialkowsky & Zickgraf, 1959; see also Michl, 1961), and a closely similar system has been used for the amino acids in the hydrolysates of proteins (Richmond & Hartley, 1959). These authors used electrophoresis at high voltages (e.g.…”
