In the tetragonal phase of gamma-aminobutyric acid, C4H9NO2, the single type of molecule adopts a partially folded zwitterionic form. Whereas in the previously characterized monoclinic phase the partially folded zwitterionic molecules exhibit a gauche conformation with respect to the C2-C3 bond, in this phase the molecules exhibit a trans conformation. The altered pattern of intramolecular N...O distances may be of significance with respect to the neurotransmission behavior of this substance… 
Broadband terahertz recognizing conformational characteristics of a significant neurotransmitter γ-aminobutyric acid
γ-Aminobutyric acid (GABA) is the chief inhibitory neurotransmitter in the central nervous system, its conformational behavior is critical for selective biological functions and the process of signal
Terahertz Time Domain Spectroscopy of Amino Acids and Sugars
A time-domain spectrometer for use in the terahertz (THz) spectral range was designed and constructed. Due to there being few existing methods of generating and detecting THz radiation, the
Engineering a GABA endowed with pharmacological CNS activity when given by an extracerebral route
It is shown herein that extracerebral administration may be, however, pharmacologically effective in controlling experimental convulsive attacks when GABA is submitted to sublimation under vacuum just before use.
