Their chemical characteristics are very similar as well. What is Glutamine  This cyclic process is known as the glutamate-glutamine cycle. However, your body is able to convert either amino acid into the other depending on need. Neurons are unable to synthesize either the excitatory neurotransmitter glutamate, or the inhibitory GABA from glucose.Discoveries of glutamate and glutamine pools within intercellular compartments led to … Deamidation of glutamine via glutaminase produces glutamate a precursor of gamma-amino butyric acid, a neurotransmission inhibitor. Glutamic Acid acts as an important neurotransmitter and is involved in the synthesis of other neurotransmitters, such as GABA. Initially, glutamic acid was produced synthetically but fermentation of glutamic acid was developed in 1957 and is today the common way of production. BUT, there is a potential dark side. “Glutamine.” University of Maryland Medical Center, Available here. For the chemists among us, MSG is a salt of L-glutamic acid, where one of the hydrogen ions is replaced by a sodium. In the body glutamic acid turns into glutamate.
