Definition

Target type: biologicalprocess

The chemical reactions and pathways involving glutamate, the anion of 2-aminopentanedioic acid. [GOC:go_curators]

Glutamate metabolism is a crucial biological process that plays a central role in numerous cellular functions, including neurotransmission, energy production, and detoxification. It involves a complex network of enzymatic reactions that convert glutamate, a non-essential amino acid, into various metabolic intermediates. Glutamate is synthesized from α-ketoglutarate, an intermediate of the citric acid cycle, through amination catalyzed by glutamate dehydrogenase. It can also be synthesized from glutamine through the action of glutaminase. Glutamate is the primary excitatory neurotransmitter in the central nervous system. It binds to glutamate receptors on postsynaptic neurons, triggering depolarization and ultimately leading to the generation of action potentials. Glutamate metabolism also plays a significant role in the regulation of energy production. It can be converted into α-ketoglutarate through deamination by glutamate dehydrogenase, which then enters the citric acid cycle for ATP production. In addition to its roles in neurotransmission and energy metabolism, glutamate is also involved in detoxification pathways. It can be converted into glutamine, a non-toxic form of ammonia, by glutamine synthetase. This reaction is essential for removing excess ammonia from the body, which is a toxic byproduct of protein metabolism. Glutamate metabolism is tightly regulated to maintain cellular homeostasis. Dysregulation of this process can lead to various pathological conditions, including neurodegenerative diseases, epilepsy, and metabolic disorders.'
